Under Cover Trivia Quiz

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.

Answer: kidney

The word 'renal' pertains to kidney. Each kidney is surrounded and protected by a tough, outer layer of fibrous tissue called the renal capsule. This in turn is encased in fatty tissue.

Answer: heart

The pericardium is a sac which envelopes the heart. It's comprised of two layers, a tough fibrous outer layer called the fibrous pericardium, and an inner serous layer, the serous pericardium. The fibrous pericardium allows for attachment to nearby vessels and structures.

The serous pericardium is further divided into two layers, a parietal layer lining the inner surface of the fibrous pericardium, and a visceral layer which lines the outside of the heart. This visceral layer is called epicardium.

Answer: Glisson's

The Glisson's capsule was named after Francis Glisson, a British physician. The Bowman's capsule is found in the kidneys. It is a cup-shaped structure concerned with the filtration process which takes place within the kidneys. Otic capsule encloses the inner ear. Articular capsule encloses joints.

Answer: uterus (womb)

The uterine wall is divided into three layers :- the endometrium or inner layer, the myometrium middle layer and the perimetrium which is the outer layer. The ovaries are the female gonads, concerned with production of eggs. The Fallopian tubes transport these eggs to the uterus.

The spleen is an abdominal organ located near the pancreas. Part of its function is to remove old red blood cells from within the blood.

Answer: Arteries and veins.

Arteries and veins have three layers. The outer layer is called the tunica adventitia. It serves to anchor the blood vessels to nearby organs and structures within the body. Capillary walls consists of a single layer only, which allows for exchange of oxygen , nutrients, and waste products between the blood and cells. In the lungs they facilitate gaseous exchange.
Eustachian tubes connect the pharynx to the inner ear. Fallopian tubes form a passageway from the ovary to the uterus.

Answer: periosteum.

The periosteum is comprised of tough fibrous tissue which covers the external surface of bones. It allows for attachment of muscles and tendons.
Articular capsule surrounds joints. Pleura lines the external surface of the lungs, while the perimetrium lines the outer surface of the uterus.

Answer: testes

A tough white layer of connective tissue covers each testis. This layer is known as the tunica albuginea testis.
Of the organs listed, the testes are the only sperm producing ones. Ovaries produce eggs. The prostate gland secretes prostatic fluid. The spleen is an abdominal organ concerned with the removal of aged red blood cells from the circulation.

Answer: meninges.

Apart from the skull and scalp, the brain is protected by three thin layers of membrane called the meninges. They are the pia mater, arachnoid mater and dura mater. Inflammation of the meninges is referred to as meningitis.
The myelin sheath is the fatty, white outer covering of nerve fibers. It serves as insulation and protection for these nerve fibers. In addition, it facilitates transmission of impulses. Cranium is the part of the skull bone which covers the brain.
Plasmalemma refers to cell membrane.

Answer: A synovial joint ( for example the hip joint )

The articular or joint capsule is a double layered sac which surrounds synovial joints. This sac contains synovial fluid which helps to lubricate the tissue within the joint cavity, hence preventing friction.
An artery is a type of blood vessel. The spinal cord is encased in the vertebral column or back bone.
The thyroid gland is an endocrine structure located at the base of the neck. Its encased in a thyroid capsule.
