1. Which part of the brain is responsible for processing sensory information?

• A. Frontal lobe
• B. Parietal lobe
• C. Occipital lobe
• D. Temporal lobe

Correct answer: B

Rationale: The parietal lobe of the brain is responsible for processing sensory information such as touch, temperature, and pain. It integrates sensory information from various parts of the body, allowing an individual to perceive and respond to different stimuli. Functions like spatial awareness and perception of the body's position in space are also associated with the parietal lobe. The frontal lobe is responsible for functions like decision-making and personality. The occipital lobe is primarily involved in visual processing, and the temporal lobe plays a role in memory and auditory processing.

2. Which cut is considered a cross section?

• A. A sagittal or frontal section
• B. A cut along the coronal plane
• C. A cut along the median plane
• D. A cut through the transverse plane

Correct answer: D

Rationale: The correct answer is D: A cut through the transverse plane. A transverse plane cut, also known as a cross-section, divides the body or an organ into superior and inferior portions. This type of cut is perpendicular to the long axis of the body and is commonly used in medical imaging to display internal structures and organs in a horizontal view. Choices A, B, and C are incorrect because a sagittal or frontal section (A) divides the body into left and right portions, a cut along the coronal plane (B) separates the body into anterior and posterior parts, and a cut along the median plane (C) divides the body into equal left and right halves.

3. Which is a secondary defense for the body against pathogens?

• A. Tears
• B. Urine
• C. Inflammation
• D. Mucus

Correct answer: C

Rationale: Inflammation is a secondary defense mechanism for the body against pathogens. When tissues are injured or infected, inflammation occurs as a protective response involving increased blood flow, white blood cell migration, and tissue repair. This process helps contain and eliminate pathogens, preventing them from spreading further in the body. Tears (Choice A) are a primary defense containing lysozyme and other antimicrobial agents. Urine (Choice B) is typically considered a non-specific defense mechanism due to its flushing action in the urinary tract. Mucus (Choice D) acts as a physical barrier and traps pathogens, also considered a primary defense mechanism.

4. Which gland is often referred to as the 'master gland'?

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Pineal gland

Correct answer: B

Rationale: The pituitary gland is often referred to as the 'master gland' because it controls the release of hormones from other endocrine glands in the body. It secretes a variety of hormones that regulate various bodily functions and play a crucial role in maintaining homeostasis. The thyroid gland (Choice A) plays a role in regulating metabolism, the adrenal gland (Choice C) secretes hormones involved in stress response, and the pineal gland (Choice D) produces melatonin to regulate sleep-wake cycles, but they are not known as the 'master gland' due to their functions.

5. Which part of the brain monitors and controls the body's movement?

• A. Top, middle portion of the parietal lobe
• B. Back of the head
• C. Front portion of the parietal lobe
• D. Around the auditory cortex

Correct answer: C

Rationale: The correct answer is the front portion of the parietal lobe. The motor cortex, located in this area, is responsible for planning, controlling, and executing voluntary movements. It plays a crucial role in coordinating the body's movement. Choice A, the top, middle portion of the parietal lobe, is incorrect as this region is more involved in processing sensory information rather than controlling movement. Choice B, the back of the head, is incorrect as it typically refers to the occipital lobe responsible for processing visual information. Choice D, around the auditory cortex, is incorrect as the auditory cortex is primarily involved in processing auditory information, not controlling body movement.
