Question

What nervous system cell conducts the impulses making all nervous system functions possible? glial cell Schwann cell neuron neuroglial cell p 4 of 14

Answer 1

Ans) Neuron

Explaination:

The actual nerve cell is the neuron. It is the "conducting" cell that transmits impulses and the structural unit of the nervous system.

Ans) macrophage

Explaination:

There are three types of glial cells in the mature central nervous system: astrocytes, oligodendrocytes, and microglial cells.

Ans) one axon and one or more dendrites

Explaination:

They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons. The number of dendrites on a neuron varies.

The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.

Ans) afferent --> interneuron--> efferent

Explaination:

Three types of neurons are involved in this reflex arc, but a two-neuron arc, a reflex is called the reflex arc. It consists of an afferent (or sensory) nerve, usually one or more interneurons within the central nervous system, and an efferent (motor, secretory, or secreto-motor) nerve.
