A&P Nervous 1

supplies the muscles of the posterior aspect of the arm and forearm

supplies the anteromedial muscles of the forearm and most of the muscles of the palm

largest nerve arising from the lumbar plexus

the largest nerve of this plexus and also the largest nerve in the body

between the dura matter and the arachnoid

between the vertebral walls and the dura matter. Which is filled with fat, connective tissue, and blood vessels

(tough mother) the outer layer

between the arachnoid and the pia matter

gives rise to nerves that supply the upper extremities

gives rise to the nerves that supply the lower extremities

(spider-like) the middle meninx

the spinal cord is covered by 3 layers of connective tissue called

deep groove running along its entire length

shallow groove running along its length

neurons that transmit information from receptor in the body to the central nervous system

nerve cells that transmit information from the central nervous system to the muscles and glands

other neurons located entirely in the brain and spinal cord, transmit impulses from sensory neurons to motor neurons

neurons with only a single cellular process. These neurons are ALWAYS affarent neurons; their single process is an axon, and their dendrite-like endsconnect directly to the axon.

neurons with more that two cellular processes (many dendrites, but only one axon) These are either efferent or association neurons.

multipolar neuron

unipolar neuron
