Nervous tissue is made up of | Nerve cells --neurons |
Neurons are comprised of | Cell Body, Dendrites, Axon, Terminal |
Glial | acts as support cells of NS, Form myelin on the axons of neurons, |
Dendrites | Recieve electrical signals and conduct those signals toward the cell body |
Cell body | Houses the nucleus and a number of organelles critical to the function of the nuron |
Axon | projects off the cell body and transmits the electrical signal down the axon in one direction toward the terminal |
Terminal | Is adequately stimulated releases a chemical to carry the message to the next nearon in line |
Impulse | When the axon transmits information |
Synapse | Interactiong between the terminal and another neuron or muscle |
Myelin | Insulation covering found on axons, made of glial cells, significant to transmit signals rapidly |
Neurotransmitters | Chemical released by terminal. |
Why are neurotransmitters needed? | For contraction of the muscle to take place |
Neuromuschular synapse | Synapse between motor neurons and the muscles |
Motor unit | A given motor neuron and all the muscle fibers it intervates |
CNS | Brain and spinal cord |
PNS | Visceral and somatic |
Visceral can futher be divided into | motor and sensory |
Visceral motor can be divided into | sympathic and parasympathic |
Somatic can be divided into | motor and sensory |
