Essay on Human Brain: The nervous system of man and other group of vertebrates is divided into three main parts: Central nervous system CNS comprising brain and spinal cord.
These two types are nerve cells and neuroglia. A nerve cell is a nervus cell that transmits urges of the nervous system.
Three chief parts make up a nerve cell: The cell organic structure of a nerve cell contains the karyon and cytol. The axon behaviors impulses off from the cell organic structure and is off from the cell organic structure a individual slender projection from the cell organic structure.
A dendrite sticks out off the cell organic structure. It is shaped slightly like a tree subdivision. Neuroglia is a type of connective tissue that supports the nerve cells. Neuroglia protects the nervous system alternatively of carry oning urges. Neuroglia use a procedure called phagocytosis to acquire rid of any unwanted substances.
Neuroglia semen in three types ; astrocytes, microglia, and oligodendrocytes. Astrocytes are cells that possess many procedures for fond regard. Astrocytes are more plentiful than any other neuroglia, and are merely present in the cardinal nervous system. Astrocytes combined with the walls of a blood capillary, prevent harmful substances from go throughing from the blood to the encephalon.

Microglias have branch like procedures stick outing from their organic structures. The intent of microglia is to take dust, waste merchandises, and pathogens from nervous tissue.
FUNCTIONS OF THE NERVOUS SYSTEM 1. Sensory input. Sensory receptors detects external and internal stimuli. 2. Neuroglia are support cells that perform a variety of functions. Neuroglia cells account for (see Clinical Focus Essay) 1. Following injury to . The nervous system is made up of neurons, specialized cells that can receive and transmit chemical or electrical signals, and glia, cells that provide support functions for the neurons by playing an information processing role that is complementary to neurons. A neuron can be compared to an electrical wire—it transmits a signal from one place to another. Name the two primary components of the central nervous system (CNS). Describe the protective membranes associated with the CNS. Differentiate between afferent and efferent nerve structure and function. The central nervous system consists of the brain and the spinal cord.
Microglia addition in figure when there is an hurt or infection of the tissue. Oligodendrocytes have procedures that protrude from their organic structure and spiral around axons. Oligodendrocytes chief intent is to be an electrical dielectric and assist rush the conductivity of nervus urges.
The peripheral nervous system transmits centripetal and motor urges to and from the cardinal nervous system and other parts of the organic structure.The following outline is meant to serve as an introduction to the general structures of the nervous system and their corresponding functions, with a focus on the nervous system’s role in motor.
Apr 27, · Neurons or nerve cells - Structure and function | Human Anatomy | Biology The nervous system is an essential part of the human body that helps in . Like the heart, lungs, and stomach, the nervous system is made up of specialized cells.
These include nerve cells (or neurons) and glial cells (or glia).
Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances. Glia are also essential to nervous system function, but they work .
There are two main types of cells in the nervous system. These two types are neurons and neuroglia.

The four major divisions of the brain are the. To describe the functional divisions of the nervous system, it is important to understand the structure of a neuron. Neurons are cells and therefore have Sensory input for autonomic functions can be from sensory structures tuned to external or internal environmental stimuli.
from other neurons or sensory cells enteric nervous system.
