Structural and functional unit of the Nervous System

nerve cells

Specialized to conduct electrical signals/impulses thru its membrane.

nerve cells

Receive stimul and transduce into nerve mouses for tansfer to another neuron

receptive

Processing impulse on the hugher certer

integrative

Initiating motor response and transduce the impulse to affector

motor

Most neurons have three main parts

cell body, dendrites, axon

often large, with a large, euchromatic nucleus and prominent nucleolus

cell body

also known as Nissi bodies or Nissi granules. are large masses of free polysomes and RER indicating the cells high rate of protein synthesis

nissi substance

thick at the base and taper to a minimum diameter of about 0.5 microns.

dendrites

A highly branched cytoplasmic extension that receives input from other neurons or receptor cells

dendrites

long, thin, cylindrical projection typically longer than dendntes

axon

conducts and carries impulses and stimuli away from the nerve cell bodies

axon

generates nerves impulses (action potentials) away from the cell body/soma

axon

Lacks Nissis bodies and does not stain with routine histological stains.Transmiting part of neuron

axon

Protects the cell

cell membrane

Generates impulse in ine neuron

axon hillock

Allow ditlusion of tons

mode of ranvier

Produces the myein sheath

schawn cell

Forms junctions with other cells

axon terminal

Increases the speed of the signal

myelin sheath

Controls the entire neuron

nucleus

usually have several dendrites and one axon

multipolar neurons

Most common. most neurons in the brain and spinal cord

multipolar neurons

They include motor neurons, which control skeletal muscles, and interneurons, which relay information between neurof

multipolar neurons

Have one main dendrite and one axon, found in retina pf the eye, inner ear, olfactory area of the brain. They are responsible for transmitting information related to sight, smell, or hearing

bipolar neurons

Sensory neurons that begin in the embryo ad bipolar neurons, long cylindrical processes that propagate action potentials. Found primarily in the afferent division of the pns

unipolar neurons

Do not produce action potentials, but regulated electrical changes of adjacent cns neurons

anaxonic neurons

Transmit information from sensory receptord in the skin, or the internal organs towards the cns for processing

sensory neurons

Transmit information awar from the cns towards some type of effector

motor neurons

Located between motor and sensory pathways. Highly involved in signal integration

interneurons
