In this article we will discuss about:- 1. Classification of Nerve Fiber 2. Properties of Nerve Fiber 3. Role of Calcium in Nerve Function. Classification of Nerve Fiber: Based on the presence or absence of myelin sheath, they are classified into myelinated or non-myelinated nerve fibers. In the peripheral nervous system, the Schwann cells are responsible for the formation of [...]
In this article we will discuss about the meaning and myesthenia gravis disease of neuromuscular junction. Meaning of Neuromuscular Junction: Neuromuscular junction (Fig. 2.14) is a functional junction between a nerve fiber and a muscle fiber. As the motor nerve approaches this junction, it loses the myelin sheath and the bare nerve expands. This expansion is known as the sole [...]
In this article we will discuss about the meaning and blocking of neuromuscular transmission. Meaning of Neuromuscular Transmission: It is the process by which the nerve action potential is converted into a muscle action potential. Events involved in the neuromuscular transmission are: i. Action potential reaching the motor neuron terminal. ii. Depolarization of motor neuron terminal. iii. Calcium ion influx [...]
