Q1. What are the two organs that compose the CNS, and what is their primary function?

Background

Topic: Central Nervous System (CNS) Overview

This question tests your understanding of the basic anatomical components of the CNS and their main roles in the body.

Key Terms:

• CNS: Central Nervous System

• Organs: Structures that carry out specific functions

Step-by-Step Guidance

1. Recall the two main organs that make up the CNS. Think about the structures protected by the skull and vertebral column.

2. Consider the primary function these organs share, which is related to processing and integrating information.

3. Write down the names of these organs and describe their shared function in a sentence.

Q2. What are the new directional terms associated with the CNS: rostral and caudal?

Background

Topic: Anatomical Directional Terms

This question is about understanding anatomical terminology used to describe locations within the CNS.

Key Terms:

• Rostral: Toward the nose or front

• Caudal: Toward the tail or back

Step-by-Step Guidance

1. Define each term based on its Latin root and anatomical context.

2. Think about how these terms are used to describe positions in the brain and spinal cord.

3. Write a brief description for each term, relating it to the CNS.
