2 systems in our body that control homeostasis
|
endocrine and nervous systems and they communicate with each other though they function quite differently
|
|
neurons communicate with...
|
electrical impulses and they come quickly and end quickly
|
|
the endocrine system comunicates through
|
chemically via hormones and their effects are gradual
|
|
master cell of the nervous system
|
neuron
|
|
the only one function of the nervous system
|
maintain homeostasis
|
|
define periphery
|
everywhere in the body except the brain and spinal cord
|
|
3 groups of neurons and their locations
|
sensory-periphery
association-brain and spinal cord motor-periphery |
|
job of sensory neurons
|
monitor everything
|
|
job of association neurons
|
receive all info from sensory neurons, analyze it, then decide on an appropriate response
|
|
job of motor neurons
|
carry out the response decided on by the association neurons
|
|
what must the sensory and motor neurons always connect through
|
the association neurons so that there can be analysis
|
|
2 major divisions of the nervous system
|
CNS-central nervous system
and PNS-peripheral nervous system |
|
The CNS is made up of what
|
the brain and spinal cord
which is comprised exclusively of association neurons |
|
the peripheral nervous system runs what two groups of neurons
|
sensory-to brain
and periphery-from brain |
|
2 subgroups of the PNS
|
somatic nervous system
and autonomic nervous system |
|
somatic nervous system is for
|
voluntary
|
|
autonomic nervous system is for
|
involuntary
|
|
sensory neurons of the somatic nervous system originate where
|
in the skin
|
|
all sensory neurons of the skin belong to the
|
somatic nervous system
|
|
the motor neurons of the somatic nervous system
|
connect to the bones of the moving skeleton and is voluntary
|
|
autonomic nervous system has sensory neurons that come from
|
the major organs
|
|
autonomic nervous system has motor neurons that go to
|
the major organs
|
|
The motoir neurons in the autonomic nervous system are sent out via the
|
sympathetic and parasympathetic nervous systems
|
|
the sympathetic and parasympathetic nervous systems will either
|
speed up or slow down an organ
|
|
the CNS is divided into the
|
brain and spinal cord
|
|
peripheral nervous system is divided into the
|
somatic and autonomic nervous system
|
|
The autonomic nervous system is divided into
|
sympathetic and parasympathetic nervous systems
|
|
sensory neurons of the somatic nervous system come in from
|
the skin
|
|
motor neurons of the somatic nervous system go out to the
|
skeletal muscles
|
|
where do sensory neurons of the autonomic nervous system originate
|
major organs
|
|
motor neurons of the autonomic nervous system go out to
|
major organs
|
|
two potential branches that motor neurons of the autonomic nervous system can travel out on
|
sympathetic and parasympathetic
|
|
sympathetic and parasympathetic nervous systems will have imposing effects on
|
organs...
one will always speed up the organ and one will always slow down an organ |
