Question 1

Which of the following does the term 'mental' refer to?

Accepted Answer

Chin

Answer

In anatomical terminology, the term 'mental' specifically refers to the chin or the mentum region of the face. This term is derived from the Latin word 'mentum,' meaning chin. For example, the mental protuberance is a feature of the mandible (jawbone) located at the chin.

Question 2

Which group of leg muscles allows a person to stand on his or her toes?

Accepted Answer

Plantar flexors

Answer

Plantar flexion is the movement that increases the angle between the foot and the leg, essentially pointing the toes downwards. The muscles responsible for this action, such as the gastrocnemius and soleus, are called plantar flexors. Standing on one's toes requires strong plantar flexion to lift the heel off the ground.

Question 3

What blood protein is responsible for regulating the blood's osmotic pressure?

Accepted Answer

Albumin

Answer

Albumin is the most abundant protein in human blood plasma and plays a crucial role in maintaining osmotic pressure. It helps to keep fluid within the blood vessels, preventing it from leaking into surrounding tissues. This function is vital for regulating blood volume and blood pressure.

Question 4

Which of these does not have apocrine sweat glands?

Accepted Answer

Fingers

Answer

Apocrine sweat glands are a type of sweat gland primarily found in specific areas of the body, including the axilla (armpits), perianal region, and ear canal (ceruminous glands are modified apocrine glands). They are not typically found on the fingers, which primarily contain eccrine sweat glands responsible for thermoregulation.

Question 5

Which damaged nerve results in "winging" of the scapula?

Accepted Answer

Long thoracic nerve

Answer

The long thoracic nerve innervates the serratus anterior muscle, which is responsible for protracting the scapula and holding it against the thoracic wall. Damage to the long thoracic nerve weakens or paralyzes the serratus anterior, leading to a condition known as 'winging of the scapula,' where the medial border of the scapula protrudes posteriorly.
