nervous system Flashcards
1
Q
NS is responsible for
A
- sensory perception
- cognitive function
- motor function
- regulatory function
2
Q
all diverse activities can be grouped into 3 basic functions:
A
- sensory output to NS
- integration of info by Ns
- motor output to cause change by Ns
3
Q
NS: two systems
A
- peripheral -all nerves outside of CNS
- central -brain and spinal cord
4
Q
CNS: controls muscles:
A
motor cortex
5
Q
CNS: thinking
A
frontal lobe
6
Q
CNS: speech and sounds:
A
temporal lobes
7
Q
CNS: basic functions (breathing)
A
brain stem
8
Q
CNS: processes sensory info:
A
sensory cortex
9
Q
CNS: vision
A
occipital lobe
10
Q
CNS: coordinates movement:
A
cerebellum
11
Q
peripheral nervous system:
A
- efferent nerves out of CNS
- motor division separates into somatic and autonomic ns
12
Q
Autonomic ns
A
separates into sympathetic and parasympathetic ns
13
Q
neuron features
A
- dendrites
- cell body
- axon
- axon terminals
- myelin sheath
- nodes of Ranvier
- nucleus
14
Q
types of neurons:
A
- unipolar
- Bipolar
- Multipolar
- Psuedounipolar
15
Q
neurons sensory division
A
afferent
carry info from external environment + body to CNS
e.g pain, temp, position
