Kennedy Dragna Nervous
P.6
Major Functions of the nervous system
Memory and learning
Programming of spinal cord reflexes
Voluntary control of movement
Control of body's internal environment to maintain 'homeostasis'
major divisions and subdivisions of the nervous system
peripheral nervous system (PNS)
the autonomic nervous system
the somatic nervous system
central nervous system (CNS)
the cerebellum
the pons
the midbrain
the medulla
the spinal cord
the diencephalon
the cerebral hemispheres
tissues (structure and function of neurons and neuroglia)
Neuroglia are supporting cells that provide physical sport, remove debris, and provide electrical insulation
Neurons are highly specialized nerve cells that generate and conduct nerve impulses
classification of neurons
motor neurons
sensory neurons
interneurons
connective tissue coverings
perimysium
endomysium
epimysium
major parts and functions of the brain
cerebellum
coordinates muscle movements, maintain posture, and balance
brainstem
acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.
cerebrum
remembering, problem solving, thinking, and feeling
major parts and functions of the spinal cord
The spinal cord is a column of nerves that travels through the spinal canal
Thirty-one pairs of nerves branch out through vertebral openings, these nerves carry messages between the brain and muscles.
Motor Functions - directs your body's voluntary muscle movements
action potential and the nerve impulse
a electrical charge that travels along the membrane of a neuron
cranial nerves
Optic nerve
Oculomotor nerve
Olfactory nerve
Trochlear nerve
Trigeminal nerve
Abducens nerve
Facial nerve
Vestibulocochlear nerve
Glossopharyngeal nerve
Vagus nerve
Accessory nerve
Hypoglossal nerve
spinal nerves
In humans there are 31 pairs of spinal nerves
8 cervical
5 lumbar
12 thoracic
5 sacral
1 coccygeal
neurotransmitters
norepinephrine
serotonin
dopamine
GABA
acetylcholine
glutamate
compare and contrast for autonomic nervous system
The somatic nervous system causes contraction of skeletal muscles
The autonomic nervous system controls cardiac and smooth muscle
reflex arc (major parts and functions)
effector target
integration center
