ANATOMY

Detailed explanation-1: -Nucleus of the neuron is large and round and is usually centrally located. In some cells, masses of deeply staining chromatin are visible in the nucleus.

Detailed explanation-2: -Neurons have a nucleus that contains genes. Neurons contain cytoplasm, mitochondria and other organelles. Neurons carry out basic cellular processes such as protein synthesis and energy production.

Detailed explanation-3: -The cell body is the spherical part of the neuron that contains the nucleus and connects to the dendrites, which bring information into the neuron, and the axon, which sends information to other neurons. The job of the cell body is to control all of the functions of the cell.

Detailed explanation-4: -Neurons are often actively synthesizing lots of protein so they have an extensive network of rough endoplasmic reticulum (rough ER) and a large and prominent nucleolus (the organelle inside the nucleus where ribosomal RNA is made). The axon is part of the output region of the neuron.

Detailed explanation-5: -Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3). Within the cell body is a nucleus (2), which controls the cell’s activities and contains the cell’s genetic material.
