ANATOMY

Detailed explanation-1: -Nissl bodies are the chromatophilic substance found in the cell body of neurons. They give cells their color and are responsible for maintaining the shape and size of cells.

Detailed explanation-2: -There are clusters of rough endoplasmic reticulum (not shown in Figure 1) that are called Nissl bodies or are sometimes referred to as chromatophilic substances.

Detailed explanation-3: -Axonal transport is the process by which nerve cells transfer substances between the cell body and axon tip. Axonal means anything relating to an axon. Cargoes can be delivered in two directions.

Detailed explanation-4: -In general, mitochondria move in the anterograde direction (away from the soma) using a family of kinesin motors, and move in the retrograde direction (toward the cell body) using the dynein motor 21.
