|
|
Term
| Identify which area of the body is served by the brachial plexus. |
|
Definition
| The brachial plexus serves the skin and muschles of the upper appendage. |
|
|
Term
| Identify the areas served by the lumbar plexus. |
|
Definition
| The lumbar plexus serves the skin and muscles of the abdominal wall, external genitalia and part of lower limb. |
|

| What is the function of the nervous system? |
|
Definition
| At the most basic level, the function of the nervous system is to send signals from one cell to others, or from one part of the body to others. |
|
|
Term
| What is the role of nerves in our body? |
|
Definition
|
|
Term
| What makes up the Central Nervous System (CNS)? |
|
Definition
| The CNS consists of the brain and spinal cord. |
|
|
Term
| What does the Peripheral Nervous System consist of? |
|
Definition
| The PNS consists of all nervous tissue outside the CNS. This includes all nerves of the body. |
|
|
