the nervous sys is responsible for ....
.. all the activity of the body. everything!
information is recieved through
both internal and expternal sensory receptors
the nervous sys can be divided into two systems...
the PNS and the CNS
the CNS is composed of...
the brain and the spinal cord
the PNS is comprised of...
the cranial nerves and the spinal nerves (all nerves except brain itself and spine itself)
nervous tissue consists of two basic types of cells:
neurons and neuroglial cells
neurons are...
indiv. nerve cells capable of conducting electrical impulses in response to a stimulus
neurons have three basic parts....
... the dendrites, the body, and the axon.
dendrites are...
highly branched portions of the neuron that rec's signals
nerve body contains...
the nucleus and other organelles of the cell
