Sensory fuction( gathering information):: inside body?
|
like ion/ nutrient levels
|
|
|
Sensory fuction( gathering information):: Outside Body?
|
temperature, sounds, light, oxygen levels
|
|
|
Integrative functions (bringing information together):
|
thoughts or decision making + sensations or perceptions
|
|
|
Motor Function : respnse to sensory input
|
muscle contraction + Gland activation

|
|
What are the divisons of the nervous system?
|
Central vs. Peripheral
Autonomic vs. Somatic Sympathetic vs. Parasympathetic |
|
|
What is a Neuron and what is Parts of a Neuron?
|
Neurons react to changes and conduct impulses
Parts: 1. Cell Body (contains nucleus 2. Dendrites (receive impulse) 3. axons (carry impulse away) |
|
|
Neuroglia
|
surrounding or between neurons
give support to neurons aka glial cells |
|
|
5 types of Neuroglia cells?
|
1. Astrocytes
2. Ependymal 3. Microglial 4. Oligodendrocytes |
|
|
Astrocytes
|
*star shaped
*found between nervous tissue and blood cells *Help regulate ion/nutrient levels. |
|
|
Ependymal
|
*squamous shaped
* inner linings of special areas of brain |
|
|
Microglial
|
*mobile cells
*prtects CNS from infection |
|
|
Oligodendrocytes
|
*surround axons of CNS
*form myelin, but no sheath |
|
|
Schwann
|
*surrounds axons of PNS
*found within a sheath (like a sock) *speeds conduction of impulses *form "white matter" of nervous tissue *Form nodes of ranvier *gaps between cells |
