The Central Nervous System
The main pathway fro information connecting the brain and peripheral nervous system
Peripheral Nervous System
Carries information to and from the CNS through nerves
Automatic nervous system
regulates for the involuntary movements of the cardiac muscles and the smooth muscles of the internal organs
The Sympathetic Nervous System
a part of the ANS
responsible for involuntary responses
such as the fight or flight response or sweating when nervous
Parasympathetic Nervous System
apart of the ANS
adjusts the body back to resting state after being altered by the sympathetic system
The Somatic Nervous System
controls skeletal muscles
has both afferent and efferent nerve fibres
Afferent Muscle fibres
sensory
sends information to the CNS
Efferent Muscle fibres
motor
sends instructions to the skeletal muscles
Cerebral reflex
From the brain
Spinal reflex
From the spinal cord
Autonomic reflexes
from the smooth and cardiac muscles
regulate digestion, elimination, ect
Somatic reflexes
affects the skeletal muscles
cause the stretch reflex and withdrawal reflex
Neutrons
Transmit information to one another
The Reflex Arch
Allows an organism to respond quickly from sensory neutrons
Sensory Neuron
Afferent Neutron- the neutron that arrives at the interneuron
Motor Neuron
Efferent Neurons- exits the interneuron
Proprioceptors
Sensory receptors located in tendons, muscles, joints, and the inner ear
Muscle Spindle
The means by which muscles constantly and automatically adjust to the demands asked of them
Synapse
Neuronal junction - the site of transmitting of electric nerve impulses between two nerve cells (neurons)
Monosyllabic reflexes
A reflex that only contains one space for an action potential to travel between a sensory and motor neutron
Polysnaptic reflexes
Spinal reflexes - one or more interneurons lie between the primary sensory fibres and the motor neutrons
Withdrawal reflex
Involves the withdrawal of a body part from a painful stimulus
The cross extensor reflex
Involves multiple synapse and muscle groups
