Long fiber with branched end is?
|
|
Cell body
|
|
|
Dendrite
|
|
|
Axon
|
|
|
Axon terminal
|
Explanation:
Detailed explanation-1: -Dendrites transmit electrical impulses towards the cyton. One of the fibres arising from the cell body is very long with a branched distal end and it is called Axon.
Detailed explanation-2: -Axon branching connects single neurons with multiple targets, which, along with the formation of highly branched terminal arbors, underlies the complex circuitry of the vertebrate CNS.
Detailed explanation-3: -The proximal portion, at the juncture with the cell body, is termed the axon hillock (Fig. 1). This region is characterized by fascicles of microtubules and a high density of sodium-dependent channels.
