MCQ IN MEDICINE

Detailed explanation-1: -The correct option is C Axon. Nerve cells or Neurons: A neuron consists of a cell body with a nucleus and cytoplasm, from which long thin hair-like parts arise. Usually each neuron has a single long part, called the axon, and many short, branched parts called dendrites.

Detailed explanation-2: -Golgi I or Golgi type I neuron is a neuron, which has a long axon that begins in the grey matter of the central nervous system and may extend from there.

Detailed explanation-3: -Every neuron has only a single axon, a thin cylindrical process that can ramify and extend up to 1m. The axon arises from a specialized region of the soma called the axon hillock where an all or none signal (the action potential) is initiated once a critical threshold is reached. The presynaptic terminals.

Detailed explanation-4: -Each neuron in your brain has one long cable that snakes away from the main part of the cell. This cable, several times thinner than a human hair, is called an axon, and it is where electrical impulses from the neuron travel away to be received by other neurons.
