Your Body Trivia Quiz

The neck is the part of the body that connects the head to the rest of the body. The main part of the neck that holds it upright is the spine, which goes up the back of the neck. Food that you eat goes down the esophagus, also in your neck. The neck also has some important blood vessels that supply blood to the brain and help keep us going.

The shoulder is the joint that connects the arm to the rest of the body. It allows for a full range of motion of the arm. It contains three bones, several muscles and ligaments, and has blood vessels and nerves that go into the arm. On the underside of the shoulder is the armpit, a dark and dank place that has sweat glands and lymph nodes.

The elbow is a joint that connects the upper to the lower part of the arm. Unlike the shoulder, the elbow is just a hinge which means that it allows for only one direction of motion. Three bones meet at the elbow, and the hard part that sticks out of the elbow is a part of your upper arm bone. That bone's medical name is the humerus, which sounds like "humorous".

This is why, when we hit our elbow and it feels like there's a jolt of electricity, it's called "hitting your funny bone".

The hand is a part of the body that is generally associated with the sense of touch. It is the most mobile of all of the body's parts, being at the end of the arm, and has many nerve endings that help us sense what we're feeling. The hand connects to the arm at a joint called the wrist.

It has five digits, meaning that with both hands we have ten; this led to our system of counting, one which is also base-10. The development as a hand for tool use was one of the main things that set humans apart from the rest of the animals. Evolving in a way that allowed humans to walk on two feet while leaving the hands free to do things was important.

The knee is an interesting joint that connects your upper leg to the lower leg, similar to the function of the elbow in the arm. Interestingly, the knee is a very complex joint. Not only is it a hinge joint which lets your lower leg move forward and back, it also lets your leg have a limited amount of rotation.

However, all of this movement means that the knee is one of the joints that is the most easily hurt. An unfortunate common injury amongst athletes is when they tear their ACL, one of the four ligaments that holds the knee together.

The foot is a part of the body at the bottom of the body. It is at the end of our leg and has to hold the weight of the entire body upon it. It is shaped in a way that allows us to move bipedally, meaning, it leaves our hands available to do other things.

There are 26 bones in the foot, and five toes, each with a fingernail. It has muscles and ligaments, and connects to the leg at a joint called the ankle.

The leg is the lower limb that helps us stand, walk, or run. The leg connects to the abdomen at the hip, a complex joint which allows it a large range of motion. Because the entire weight of the body rests on the legs, and the act of walking basically alternates the weight between each leg, the legs are the most often-injured part of the human body.

This risk increases when the activity of the legs is intensified, like dancing, jumping, and climbing.

The arm is the upper limb of the body, and is one of the main parts of the body that gets used actively. It starts at the shoulder, goes down through the elbow to the wrist and terminates at the hand and fingers. The three main bones of the arm are called the humerus, the ulna, and the radius.

The flexed arm is often used as a symbol of strength and power, while the raised arms are used to represent surrender and defeat.

The chest, also known as the thorax, is the part of the body that holds most of the organs in the body that are needed and necessary for the body to live. It connects to the head, arms, and abdomen. It is enclosed by a bone-and-cartilage structure called the ribcage which protects the two main organs in the chest, the heart and the lungs.

The ribs themselves are connected in the back to the backbone, or spine, which helps keep us upright and is a conduit for the nerves going down from the brain into the rest of the body.

The head is the part of the body that contains the brain, eyes, ears, nose, and mouth, amongst other parts. The brain is encased in a bone called the skull which protects the it from harm. Many of the important functions of the body, like thinking, emotions, and the senses are organized in the brain making it one of the most important organs in the body. Even though the head sit on top of the body, the heart pumps a steady flow of blood upwards to keep it running.
