co-ordination Flashcards
what is neuromuscular junction
synaptic connection between end of motor nerve and a muscle
types of neurons
sensory motor associated nerves
types of actions
voluantry invountary reflex action
what is reflex arc
(neural pathway that transmits the actions in the body) a single pathway that goes upto the spinal cord from receptors and return in effector muscle/organ
what are the componenets of reflex arc
5:-
receptor
sensory nerve
associated nerve
motor nerve effector organ
brain is protected by membrane and fluid called
membrane- meninges
fluid- cerebro- spinal fluid
