Coordination and response, drugs, and biotech Flashcards
what is coordination
The link between the stimulus and the response is known as coordination
what are the two types of coordination systems
nervous, endocrine (hormone) systems
How is the information sent through the nervous system?
sent through the nervous system asnerve impulses- electrical signals
A bundle of neurones is known as?
a nerve
nerve impulses
- electrical signals that pass along nerve cells known as neurones
structure of neurones
long fibre (axon) less time is wasted transferring impulse, fatty sheath (nodes) so impulse jumps from one node to the next, extentions (dendrites) so they can connect to other neurones making a network
sensory neurones
carry impulses from sense organs to cns(brain or spinal cord)
relay neurones
inside cns and connect sensory and motor neurones
motor neurones
carry impulsesfrom the CNS to effectors(muscles or glands)
cns
central neurone system
whats the cns made of
brain and spinal cord
