Anatomy

1. What is the muscular sac in the female body that nourishes and protects a developing fetus during pregnancy?

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus, also known as the womb, is a muscular sac in the female reproductive system where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment, support, and protection to the developing fetus until birth. The ovaries produce eggs, the fallopian tubes transport eggs to the uterus, and the vagina is the birth canal and the organ of sexual intercourse, but the uterus is specifically responsible for nurturing and protecting the developing fetus.

2. The process of a liquid changing into a gas is called:

Correct answer: A

Rationale: Evaporation occurs at any temperature, while boiling only occurs at the boiling point of the liquid.

3. Which statement accurately defines power?

Correct answer: b

Rationale: Power measures how quickly work is done or energy is transferred or converted.

4. Which component of the nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles?

Correct answer: c

Rationale: The correct answer is C, the somatic nervous system. The somatic nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles. This system consists of motor neurons that send signals from the central nervous system to the skeletal muscles, allowing us to consciously control our movements. The autonomic nervous system (A) controls involuntary actions like heart rate and digestion, the peripheral nervous system (B) includes all nerves outside of the brain and spinal cord, and the sympathetic nervous system (D) is a division of the autonomic nervous system responsible for the fight-or-flight response. Therefore, the somatic nervous system is specifically involved in voluntary movements.

5. Which hormone, produced by the pancreas, is involved in the regulation of blood sugar levels by inhibiting the release of insulin and promoting the release of glucose into the bloodstream?

Correct answer: D

Rationale: The correct answer is D: Somatostatin. Somatostatin is a hormone produced by the pancreas that plays a key role in regulating blood sugar levels. It inhibits the secretion of insulin, which helps prevent a further decrease in blood sugar levels. Additionally, somatostatin promotes the release of glucose into the bloodstream by inhibiting the release of other hormones that would lower blood sugar levels. This dual action of somatostatin helps maintain blood sugar within a normal range. While insulin is involved in lowering blood sugar levels by promoting glucose uptake, glucagon stimulates the release of glucose from storage to increase blood sugar levels. Cortisol is a steroid hormone produced by the adrenal glands that plays a role in stress response and metabolism, but it is not directly involved in regulating blood sugar levels.

6. Which part of the spinal cord is responsible for transmitting sensory information from the body to the brain?

Correct answer: a

Rationale: The correct answer is A: Dorsal root. The dorsal root of the spinal cord is responsible for transmitting sensory information from the body to the brain. This root contains sensory nerve fibers that carry information such as touch, temperature, and pain signals from the peripheral nervous system to the central nervous system. Ventral roots, on the other hand, are responsible for transmitting motor information from the brain to the muscles. Gray matter is primarily composed of nerve cell bodies and is involved in processing information, while white matter consists of myelinated nerve fibers that facilitate communication between different parts of the nervous system. Therefore, in this context, the dorsal root is the specific structure that handles sensory information transmission.
