receive information and transmit it to other cells

came from the greek word glue

performs many functions

a pioneer in neuron-science

detailed drawing of the nervous system

his research demonstrated that nerve cells remain separate of merging to one another

the most distictive feature of a neuron

received excitation through its dendrites and conducts impulses along its axon to a muscle

highly sensitive to a particular type of stimulation, such as light, sound or touch

comes from the greek word TREE

receives information from other neurons

short outgrowths that increase the surface area available for synapses

it contains the nucleus, ribosomes, and the mitochondria

other term for soma

comes from the greek word AXIS

greek word for axon

it conveys an impulse toward other neurons, an organ or a muscle

form the walls of the capillaries

a protein mediated process that expends energy to pump chemicals from the blood into the brain

the only nutrient that crosses that blood-brain barrier in large quantities

what prepares the neuron to respond rapidly?

the amplitude and velocity of action potential are independent of the intensity of the stimulus that initiated it, provided that the stimulus reach the threshold

neurons that depend almost entirely on glucose

need of blood-brain barrier?

also known as the end bulb

the end of each branch of an axon that appears like swelling

where axon releases chemicals that cross through the junction between that neuron and another cell

brings information to the structure

carries information away from a structure

if cells's dendrites and axon are entirely contained within a single structure

also known as NEUROGLIA

held neurons together

are star-shaped around the synapses of functionally related axons

acts as a part of the immune system removing viruses and fungi from the brain

found in the brain and the spinal chord

in the periphery of the body build myelin sheaths that surround and insulate certain vertebrate axons

guide the migration of neurons and their axons and dendrites during embryonic development

the mechanism that excludes most chemicals in the vertebrate brain

shields the neurons from chemicals circulating by taking up ions and transmitters released by axons and releasing them back, it helps synchronize closely related neuron enabling axons to send messages in waves

active partners of neurons
