Nerve fibers are long extensions of neurons that transmit electrical signals throughout the nervous system. They consist of axons covered by a myelin sheath and are classified into three main types based on diameter, myelination, and conduction velocity: A, B, and C fibers. Types of Nerve Fibers: A Fibers: Myelinated with a large diameter (1-22 … Read more

A nerve impulse, also known as an action potential, is an electrical signal that travels along the nerve cells or neurons in the nervous system. It is the fundamental mechanism through which neurons communicate with each other and transmit information. Nerve impulses are crucial for processing sensory input, generating motor output, and enabling higher cognitive … Read more

The nervous system introduction is a complex network of nerves, neurons, and supporting cells that coordinate and transmit information throughout the body. It is responsible for sensing and responding to various internal and external stimuli, enabling organisms to interact with their environment and maintain homeostasis. The nervous system can be divided into two main parts: … Read more

Classification of Neuron can be based on their structure, function, or the type of neurotransmitters they release. Here’s a brief overview of the Classification of Neuron: 1. Structural classification of Neuron: a. Unipolar neurons: These neurons have a single process extending from the cell body, which later branches into an axon and a dendrite. Unipolar … Read more

Organization of Nervous System is divided into two main divisions: the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). Each of these divisions has its own subdivisions and components, which work together to coordinate and control various functions in the body. 1. Central Nervous System (CNS): a. Brain: The brain is the control … Read more

A neuron, or nerve cell, is the fundamental unit of the nervous system responsible for processing and transmitting information through electrical and chemical signals. Neurons are the building blocks of the brain, spinal cord, and nerves throughout the body. While there are various types of neurons with specialized functions, they all share a common structure: … Read more

Let’s Discuss Introduction of Nervous System in easy points: The nervous system is a complex network of neurons that transmit signals throughout the body, coordinating and controlling a wide range of functions, from voluntary movements to involuntary processes like homeostasis and internal organ regulation. Main Divisions: 1. Central Nervous System (CNS): Composed of the brain and … Read more
