Nervous System Flashcards
1
Q
Periphal nervous system
A
Nervous tissue that connect to spine and rest of body
Sends with sensory + motory neuroma
2
Q
Central nervous system
A
Brain + spinal cord
Controls most functions and responds
Connects to pns through nerves on spinal cord
3
Q
Receptor
A
Detect stimuli and change
Connected to neurons that send signals to body
4
Q
Types of receptors
A
Chemo- detect chemicals
Thermo-Temp change
Mechano- mechanical changes
Photo- detect light
5
Q
Stimuli
A
Detectable change in physical or chemical structure of an organisms internal/external environment
6
Q
How?
A
Receptor detect stimuli
Impulses sent along sensory Neuton by peripheral nervous system to spinal cord.
CNS procces information in spine
Then sent from CNS along Motory Neuron to effector
Necessary response taken.
