3 Functions of the Nervous system

1) Sensory
2) Integrative
3) Motor

1

Sensory function

1) DETECT internal stimuli via receptors
2) DETECT external stimuli via receptors
3) SEND stimuli info to CNS

2

Integrative function

1) INTERPRETATION of sensory input
2) DICTATING appropriate response to stimuli

3

Motor function

RESPONDS to stimuli by activating effectors

4

Effectors

Muscles
Glands

5

Parts of Central Nervous System (CNS)

Brain
Spinal cord

6

Parts of the Peripheral Nervous System (PNS)

Nerves
Ganglia

7

Function of CNS

INTEGRATE input to DETERMINE output

8

Types of neurons in PNS

Sensory = afferent
Motor = efferent

9

Sensory neuron function

= afferent
Move sensory input from receptors to CNS

10

Efferent neuron function

= motor
Move sensory output from brain to effectors

11

Cranial nerve functions

Move sensory info into and out of brain

12

Spinal nerve function

Move sensory info into and out of the spine

13

Enteric nervous system

.

14

2 types of Afferent neuron fibers

1) Somatic = conscious perception (skin, skeletal muscles,etc.)
2) Visceral = unconscious perception (internal organs)

15

2 types of efferent neurons

Somatic
Autonomic

16

Somatic efferent neurons move sensory input from ____ to _____

CNS to skeletal muscle

17

Autonomic efferent neurons move sensory input from ____ to ______, ______, or _______

CNS
1) smooth muscle
2) cardiac muscle
3) glands

18

2 types of autonomic neurons

1) sympathetic
2) parasympathetic
