Mixed Human Body Trivia

1. The vertebrae, collectively, make up a more complex structure, which is called what?

From Quiz Quiz and Crossword Combo #2: Body Parts

Answer: Spine

There are thirty-three vertebrae in a human's vertebral column. The upper twenty-four articulate and each have inter-vertebral discs between these bones, but the lower nine are fused in adults (five in the sacrum and four in the coccyx). The spine is divided into regions called the cervical spine, thoracic spine, lumbar spine, sacrum and coccyx. There are seven cervical vertebrae, twelve thoracic vertebrae and five lumbar vertebrae. The number of these in the cervical region is only rarely different in mammals, with the exceptions being the two sloth genera and the manatee genus. All other mammals have seven cervical vertebrae, even the giraffe but those seven vertebrae are very tall - up to 25cm. In other vertebrates, the number of cervical vertebrae can range from one cervical vertebra in amphibians, to 25 in swans. With lower articulating vertebrae, those attached to the ribs are called thoracic vertebrae, while those without ribs attached, are called lumbar vertebrae.

From Quiz The Body Beautiful

Answer: Orbicularis Oris

The orbicularis oris is a group of muscles that encircles the mouth and is used to pucker the lips, hence the nickname. Strong examples of this muscle are found in musicians whose instrument involves creating a tight seal, such as oboe players and saxophonists. The stapedius is the smallest muscle in the body, supporting the smallest bone in the body, the stapes in the middle ear, while the sartorius is the longest muscle in the body, running from the hip bone to the knee bone. The superior rectus is a muscle that attaches to the top of the eye allowing it to move upward.

From Quiz Snot Running Down His Nose

Answer: Nasal passages

What we call "snot" colloquially is dried nasal mucus, produced by the mucous membranes of the upper respiratory system (the nasal passages). This mucus serves the function of keeping the passages lubricated; warming inhaled air; and trapping dust, pollen, pollutants, and bacteria so that they can be passed from the body by sneezing. When the mucus thickens or dries, it often takes the form we refer to as "snot."

From Quiz Oh, The Human Anatomy!

Answer: Ova (Egg cell)

The ova, or egg cell, carries the genetic information for the female. All of a females ova are present in the ovaries at birth, although they are not yet mature. The ova is visible although still very small at about one-tenth of a millimeter. That is about the size of one of the periods in this answer.

From Quiz Body Parts Mix-Up

Answer: problem solving, judgement and motor function

The brain is one of the body's most vital and complex organs. It has several specialized areas that function together. The occipital lobes are correct in their belief that they should operate the brain's visual processing system. The frontal lobes are clearly out of line as they should get on with their job of problem solving, judgement and motor function. Sensation, handwriting and body position are handled by the parietal lobes, and memory and hearing by the temporal lobes. It is in the brain stem, lying between the spinal cord and the rest of the brain, that functions such as breathing and sleep are controlled.

From Quiz Every Body Neglects Me

Answer: Gallbladder

The gallbladder is a useful little organ which stores bile made by the liver until a person eats food that contains fat. When the food containing fat enters the digestive tract, the gallbladder contracts and releases its contents into the intestine. The bile then emulsifies fats, allowing them to be absorbed by the body more easily.

From Quiz Kissing, Oozing, Flowing and Leaking

Answer: Water

The human body is about fifty to seventy-five percent water, depending on a person's age, gender, health and hydration. Infants for instance are made up of about 75% to 78% water (as any parent can attest). By age one the percentage is closer to sixty-five. Males average about 60%, and women 55% because they have more curves (fatty tissue), and curves contain less water than lean tissue. When humans are thirsty they have lost two to three per cent of their total water. The human cell is 90% water. Water is essential to take in and process food, cushion joints, carry oxygen and nutrients to and from cells, and flush waste. We can survive only about three days, on average, without it.

From Quiz Don't Know Much About Anatomy....

Answer: Epidermis

The Epidermis is the outermost layer of human skin, and provides a barrier against pathogens entering the body, as well as regulating the amount of water excreted by the body.

From Quiz My Body is a Wonderland

Answer: cheekbone

Forming the prominence of the cheek, and along with the maxilla and palatine bone, providing the base (floor) for the orbit, the zygomatic bones are part of the zygomatic process. Also called the malar bone, zygomatic is a derivation of the Greek word for 'yoke'. 'High" cheekbones, those that are located higher on the face, are considered a hallmark of beauty in many cultures. So much so, that malar implants may be used to enhance a person's facial structure. Cheek augmentation can also be achieved through injections.

From Quiz My Left Foot

Answer: Hallux

Hallux, meaning great or big toe, is the name for your big toe. Although it is called big toe it is not necessarily the longest toe on your foot. The second toe is longer on people with a certain gene. Birds also have a hallux, and with them it is the backwards facing claw that allows them to grip on branches and perches. Pollex is the thumb. Phalanges is the name for the bones of the feet. Tetrapod is the name for four-limbed vertebrates.

From Quiz The Body Human

Answer: Under your nose

Your philtrum is that medial depression that lies under your nose and runs to your upper lip. It is a vestigial feature that originally helped moisture run from the mouth to the nose pad. A wet nose pad catches more dust and dirt than a dry nose pad. The philtrum can be seen on most mammals as an indentation between the nostrils and still serves its original function.

From Quiz Heal the Organ

Answer: Stomach

The stomach is a part of the digestive system of the body. This organ produces acid to aid in digestion. The increase in acid levels may lead to a complication called peptic ulcer. Gastritis is the inflammation of the stomach.

From Quiz Human Biology

Answer: The left ventricle

The left ventricle is the largest chamber because it has to pump blood throughout the whole body. The right ventricle pumps blood to the lungs only, then back to the heart. The two atria receive blood.

From Quiz I Need a Hand

Answer: several weeks

If possible, measuring and sizing of the prosthetic begins before the limb is amputated. Once the limb is amputated, the site must heal and the swelling subside before the prosthesis is fitted. The type of fitting is defined by both the amputation needed and the functionality expected from the prosthesis.

From Quiz General Human Anatomy

Answer: stapedius (muscle found in the middle ear)

The stapedius muscle is a small muscle attached to stapes (a bone found within the middle ear). Stapedius was categorized to be a skeletal muscle because it is striated and is found attached to a bone. Despite its classification as a skeletal muscle, it moves involuntarily. It only contracts when there is too much vibration by the ossicles (bones of the ear) caused by a very loud sound. It functions to dampen or lessen the volume of the sound so that the inner ear would not get destroyed.

From Quiz Anatomy 1 to 10

Answer: vermiform appendix

The vermiform appendix is believed to be a vestigial (no longer functional) organ in the human intestinal tract. Scientists believe that the appendix was used by primates before to digest plant materials such as leaves in their diet.

From Quiz What Did You Say? - The Larynx

Answer: Thyroid

The thyroid cartilage has a complex shape. It consists of two side plates called laminae that fuse in the front center of the cartilage to form the Adam's apple, which can also be called the "pomus Adamus". This angle of fusion between the two laminae varies between genders: in males, it is about 90 degrees, and 120 degrees in the female. This is why you see a more prominent bulge in the necks of males. The hyoid is actually a bone and not a cartilage.

From Quiz My Life So Far

Answer: Blue

Babies see in colour from birth. At first only strong primary colours cause any reaction, although for some reason this does not include blue. As the eyesight improves and focuses strong shades of colour and highly defined patterns are recognised. Full vision as an adult would understand it is fully developed by around a year old.

From Quiz Under Cover

Answer: Pleura

The pleura, being a serous membrane, has two layers. The inner or visceral layer covers the lungs. The outer or parietal layer lines the inner chest wall. Between these two layers is a space referred to as the pleural cavity. This cavity contains a small amount of pleural fluid which facilitates smooth, gliding movement of the lungs during breathing. Peritoneum lines the abdominal wall. Periosteun covers bones. Placenta is another name for the afterbirth, which provides oxygen and nutrients for the fetus while in utero.

From Quiz Whose Body is it Anyway?

Answer: Heart

The Bundle of His (pronounced hiss) is a nerve bundle that carries electrical signals from the AV node ("pacer") to the apex of the heart so that the heart muscle can contract upwards. Wilhelm His, Jr. was a Swiss anatomist and cardiologist.

From Quiz Human Body Basics Part IX

Answer: inner ear structures concerned with balance and proprioception (sense of position)

Fluid shifts in these canals with changes in position and move little hairs in the structure, similar to ocean currents causing sea anemones to drift. The movement of the hairs sends nerve impules signaling a change in orientation or position.
