1. Which hormone, produced by the pituitary gland, stimulates the growth and development of bones, muscles, and organs?

• A. Growth hormone (GH)
• B. Thyroid-stimulating hormone (TSH)
• C. Prolactin
• D. Follicle-stimulating hormone (FSH)

Correct answer: A

Rationale: The correct answer is Growth hormone (GH). GH, produced by the pituitary gland, is responsible for stimulating the growth and development of bones, muscles, and organs. It plays a critical role in regulating growth during childhood and adolescence by promoting cell division, protein synthesis, and tissue growth. Thyroid-stimulating hormone (TSH) functions to stimulate the thyroid gland to produce thyroid hormones, while prolactin is involved in milk production. Follicle-stimulating hormone (FSH) is primarily responsible for reproductive functions like egg development in females and sperm production in males.

2. Which skin condition is characterized by red, itchy, and inflamed patches?

• A. Eczema
• B. Psoriasis
• C. Melanoma
• D. Keloid

Correct answer: A

Rationale: Eczema is a skin condition characterized by red, itchy, and inflamed patches. It is a common condition that can vary in severity and often presents with symptoms such as dry, scaly skin, and sometimes oozing or crusting. Psoriasis, on the other hand, presents with red, scaly patches but is not typically described as itchy. Melanoma is a type of skin cancer characterized by the development of abnormal moles, while keloid is a type of raised scar that can occur after an injury to the skin. Therefore, the correct answer is eczema due to its specific symptom presentation of red, itchy, and inflamed patches.

3. Which of the following is NOT a type of epithelium?

• A. Stratified squamous
• B. Simple cuboidal
• C. Stratified columnar
• D. Pseudostratified columnar

Correct answer: D

Rationale: The correct answer is D, Pseudostratified columnar. Pseudostratified columnar epithelium is not a type of epithelium. It is a specialized form of simple columnar epithelium. Stratified squamous, simple cuboidal, and stratified columnar are all types of epithelial tissues found in the human body. Stratified squamous epithelium is found in the skin, mouth, and esophagus; simple cuboidal epithelium lines kidney tubules and glands; stratified columnar epithelium is present in parts of the respiratory tract and male urethra.

4. Which of the following best describes the function of synergists?

• A. They assist primary movers in completing specific movements
• B. They stabilize the point of origin and provide extra pull near the insertion
• C. They help prevent unwanted movement at a joint
• D. All of the above

Correct answer: D

Rationale: Synergists play multiple roles in muscle function. They assist primary movers in completing specific movements by working together with them. Additionally, synergists help stabilize the point of origin and provide extra pull near the insertion, contributing to the efficiency of movement. Furthermore, they also help prevent unwanted movement at a joint by ensuring that the intended motion is executed smoothly. Therefore, all the statements in the answer choices accurately describe the functions of synergists, making 'All of the above' the most comprehensive and precise description of their role.

5. Which of the following terms describes the enlargement of an organ or tissue?

• A. Dystrophy
• B. Atrophy
• C. Hypertrophy
• D. Eutrophy

Correct answer: C

Rationale: Hypertrophy refers to the enlargement of an organ or tissue, typically due to an increase in the size of individual cells. This can occur in response to increased workload, hormonal stimulation, or other factors. On the other hand, dystrophy refers to the degeneration and deterioration of tissue, atrophy describes the decrease in the size of an organ or tissue, and eutrophy denotes a state of normal nutrition or growth. Therefore, the correct answer is 'Hypertrophy' as it specifically relates to the increase in size or volume of an organ or tissue.
