Neuroanatomy Background Information

Create a written guide, including both the CNS and the PNS. Describes what the basic neuroanatomical structures are, where they are located, how they interact, and what function they serve.
Name the structures by using the correct technical language but to use layperson's language as much as possible elsewhere.
The neuroanatomy guide should cover the following:

1) Basic neuroanatomical structures (including the CNS and the PNS, as well as the structural packaging that protects the brain from the environment).
2) Location of these structures.
3) Functions they serve (what functions damage to these areas may affect).
4) How they interact.
Be sure to explain the information in layperson's language. Also references (it is very important).
Remember I need notes, not an essay.

.1. Neuroanatomy is the study of the structure of the neuronal system (Pinel, 2006, p. 487).

2. The Central Nervous System (CNS) consists of the brain and the spinal chord.

3. The brain is located in the skull, and the spine is located in the spinal chord.

4 The Peripheral Nervous System (PNS) consists of cranial nerves and signal nerves.

5. The PNS is composed of the somatic nervous system (SNS), and the autonomic nervous system (ANS).

6. The SNS is composed of different nerves that carry sensory signal from the skin, skeletal, muscle, joint, eye, etc.). The ANS is a part of PNS that regulates the body's internal environment.

7. The ANS is composed of different nerves that carry sensory signals from internal to the CNS, and efferent (motor) nerves carry signals away from the CNS to internal organs.

8. Sympathetic nerves are autonomic that project from the nervous system at the small of the back.

9. Autonomic nerves are located in the located back.

10. The brain is located in the skull, and the spine is located in the spinal chord. (Pinel, 2006, Numbers 1-10, located on p. 51.

11. The CN refers to the command nucleus that receives inputs from the precommand nucleus [PNS] (Carlson, 2002) that is located in the techtrum (the roof) or dorsal structure of the mesencephalon, or midbrain (Pinel, P.65).

12 The Mesencephalon has two divisions—the techtum and the tegmentum. The tectum is composed of two pairs that include, namely inferior colliculi and superior colliculi. The IC is ...
