In Anatomy & Physiology, you will have to know the structure of a neuron and how each structure functions. For instance, as a student you must be familiar with how the axon and dendrites carry electrical signals and how Schwann cells form the myelin sheath of the axon. This quiz is designed to test your knowledge on this material.
21 Δεκ 2023 · The axon hillock refers to an anatomically and functionally distinct area of the cell body which serves as the origin of the axon. It is cone-shaped and devoid of large cytoplasmic organelles such as chromatophilic substance (Nissl bodies) and Golgi apparatus.
The axon contains microtubules and neurofilaments, bounded by a plasma membrane known as the axolemma. Outside the plasma membrane of the axon is the myelin sheath, which is composed of the tightly wrapped plasma membrane of a Schwann cell.
