1. Which of the following locations is not involved in the release of hormones during stress?

Correct answer: A

Rationale: The parathyroid gland is not involved in the release of hormones during stress. It is responsible for regulating calcium levels in the blood by secreting parathyroid hormone. During stress, the adrenal cortex, posterior pituitary, and hypothalamus play crucial roles in releasing stress hormones like cortisol, adrenaline, and oxytocin. Therefore, the correct answer is the parathyroid gland, as it is not directly associated with the release of stress-related hormones.

2. The motor cortex helps the brain by monitoring and controlling the body's movement. Where is the motor cortex located within the brain?

Correct answer: C

Rationale: The correct answer is C: Front portion of the parietal lobe. The motor cortex is located in the frontal lobe, specifically in the front portion of the parietal lobe. It is responsible for planning, controlling, and executing voluntary movements. Choices A, B, and D are incorrect as the motor cortex is not located at the back of the head, top middle portion of the parietal lobe, or around the auditory cortex.

3. What structures are likely torn in a rotator cuff tear?

Correct answer: A

Rationale: In a rotator cuff tear, the most common structures torn are the tendons of the rotator cuff muscles. In severe cases, the tear may also extend to involve the surrounding ligaments. Therefore, the correct answer is A, as it accurately represents the structures that are likely to be affected in a rotator cuff tear. Choice B is incorrect as muscles are not typically torn in a rotator cuff tear. Choice C is also incorrect as ligaments are not the primary structures involved in a rotator cuff tear. Choice D is incorrect because a rotator cuff tear typically involves more than just the tendons.

4. Which structure is responsible for carrying oxygen to the cells?

Correct answer: A

Rationale: Hemoglobin, located in red blood cells, is responsible for binding to oxygen in the lungs and transporting it to tissues throughout the body. Red blood cells contain hemoglobin, making them the primary carrier of oxygen to cells. Hemoglobin is the correct answer because it is the protein within red blood cells that directly binds to oxygen for transport. Plasma is the liquid component of blood and does not carry oxygen. Platelets are responsible for blood clotting and have no role in oxygen transport. While red blood cells do carry oxygen, it is specifically the hemoglobin within them that performs this function.

5. How does a sagittal section divide the body?

Correct answer: A

Rationale: A sagittal section divides the body into right and left regions. This type of section runs longitudinally from front to back, separating the body into right and left halves. Sagittal sections are crucial for understanding the anatomical structure and orientation of various body parts. Choices B, C, and D are incorrect because a sagittal section specifically divides the body into right and left portions, not upper and lower regions, front and back regions, or between the dorsal and ventral cavities.
