What is the basic structure and function of the nervous system?

What is the basic structure and function of the nervous system?

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.

What is the basic structural unit of the nervous system quizlet?

The basic structural unit of the nervous system. It is also called a nerve cell. It consists of a cell body containing a nucleus;nerve fibers , called dendrites and a single nerve fiber(axon). A nerve fiber that carries impulses toward the cell body.

What are the 4 main structures of the nervous system?

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.

What are the basic unit of the nervous system and why is it considered so?

Neuron is called the basic unit of the nervous system because all the parts of nervous system whether it is brain or spinal cord or cranial or spinal nerves all are made of neurons.

What is the basic function of nervous system?

Your nervous system is your body’s command center. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).

What is the structure of a typical neuron?

A typical neuron consists of a cell body (soma), dendrites, and a single axon. The soma is usually compact. The axon and dendrites are filaments that extrude from it. Dendrites typically branch profusely and extend a few hundred micrometers from the soma.

Who described neurons and identified them as the basic structural unit of the nervous system?

49)). Waldeyer-Hartz used the observations of other scientists to support his claim that the neuron is the most basic structural unit of the nervous system.

What are the three basic parts of the neuron?

A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.

What is the unit of nervous system?

The basic unit of the nervous system is a nerve cell, or neuron. The human brain contains about 100 billion neurons.

What is the functional unit of the nervous system?

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.

What is the basic unit of the nervous system that carries nerve impulse?

neuron: A cell of the nervous system, which conducts nerve impulses; consisting of an axon and several dendrites. Neurons are connected by synapses.

What are the most basic elements of the nervous system?

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord . The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body. The nervous system transmits signals between the brain and the rest of the body, including internal organs.

What is the unit of structure in the nervous system called?

Neuron is the unit of nervous system: The structural and functional unit of nervous system is called neuron. It is a special type of cell with a cell body and cell processes.

What are the structures and functions of the nervous system?

The nervous system consists of the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment.

What is fundamental working unit of the nervous system?

Neuron can be considered as the basic unit of the nervous system, which processes and transmits information by means of electrochemical signals. Sensory neurons respond to external stimuli that affect the sensory organ cells. Motor neurons, on receiving signals from the central nervous system, bring about responses at the target organs.
