1.The functions of the neuronic system are: (1) Monitors the internal and external environments, (2) integrates sensory information, and (3) coordinates unbidden and involuntary responses.
2.The brain and spinal cord make up the CNS.
3.The functions of nurse cells are to regulate the environment around the neurons, allow for a supporting framework for neural tissue and playact as phagocytes. (take cares of cells)
4.Astrocytes are the largest and most numerous neuralgia. They secrete chemicals resilient to the maintenance of the blood-brain barrier. Also create structural framework for central nervous system neurons and perform repairs in damaged neural tissue
5.Oligodendrocytes and scwann cells make up myelin sheath.
6.The parts of the reflex arc are the receptor, sensory neuron, collateral, interneuron, motor neuron, and effector.
7.A cell is polarized because it separates an excess of positive charges on the outside from an excess of negative charges on the inside.
8.
9.Saltatory conduction is a type of nerve impulse conduction that allows march potentials to penetrate faster.
10.Dendrites are short branched fibers in neurons.
11.A interpretive program neuron
12.Hyperpolarization is a change in a cell tissue layer potential that makes it more negative.
13.
14.
Ions can enter or kick in the cell with the aid of membrane channel and/or aircraft carrier proteins.
15.Calcium ions are needed.
16.The steps in the generation of action potential are: (1) Na+ ions channels open in membrane, (2) the action potential propagates, (3) repolarization occurs, (4) ionic concentrations are reestablished.
17.Centrioles form mandril fibers to separate chromosomes during cell division.
18. The sodium potassium pump fails when it runs out of energy causing water to enter the cell, expands it, explodes, and it dies.
19.The PNS consists of the crainial and spinal jitteriness that come from CNS.
20.Neurotransmitters
21.Afferent are sensory neurons that receive...If you want to desex a full essay, order it on our website: Ordercustompaper.com
