Match the terms to their correct definitions. 1. cell body insulation that speeds up transmissions from other neurons 2. dendrites one long fiber with branches at the end 3. axon contains the nucleus of the cell 4. myelin sheath branching part of the neuron that receives transmissions from other neurons

Answers:

Myelin sheath 

Axon

cell body

Dendrites

Explanation:

Myelin sheath 

Myelin acts as an insulating layer, or sheath around the nerves. It constitute are protein and fatty substances. It permits electrical impulses to be sent swiftly and effectively through the nerve cells such that an injury to the myelin, will reduce impulses transmission.

Axon

The axon is transmits the signal to the synapse. It's long, thin and tendril-like. it transports electrical signal out of the cell body(soma)to the synapse.

cell body

The cell body houses the neuron that possess the nucleus. It is linked to the dendrites, which transmits information into the neuron while the axon transmits information to other neurons. Its basic function is to coordinate the entire functions of the cell.

Dendrites

Dendrites are branched protoplasmic extensions of a nerve cell that transmits the electrochemical stimulation sent from the other neural cells to the cell body, or soma, of the neuron.

age range would be the answer

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
