What are the two main parts of the nervous system and where are they found?

First, the basic functions of the nervous system are sensation, integration, and response. Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response.

What are the 2 main parts of the nervous system?

The nervous system is made up of the central nervous system and the peripheral nervous system:
  • The central nervous system includes the brain and spinal cord.
  • The peripheral nervous system includes the nerves that run throughout the whole body.

What are the 2 types of cells found in the nervous system and what does each do?

Nervous tissue contains two major cell types, neurons and glial cells. Neurons are responsible for communication through electrical signals. Glial cells are supporting cells, allowing neuron function. Though neuron shape varies, neurons are polarized cells, based on the flow of electrical signals along their membrane.

What are the two main communication systems of the body?

Humans have two types of communication systems. These are the nervous system and the endocrine (hormone) system. These systems regulate body processes through chemical and electrical signals that pass between cells.

Which two organ systems send messages throughout the body?

They must be able to respond to each other and change their responses as needed to keep the body in balance. Communication among organ systems is controlled mainly by the autonomic nervous system and the endocrine system.

What protects the brain?

The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.

Communications to maintain homeostasis occur by means of the autonomic nervous system and the endocrine system.

What are two body systems that work together and why?

For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide.

What are the two main organ that communicate to maintain homeostasis?

The endocrine and central nervous systems are the major control systems for regulating homeostasis (Tortora and Anagnostakos, 2003) (Fig 2). The endocrine system consists of a series of glands that secrete chemical regulators (hormones).

Which 2 body systems work together to get the body oxygen?

The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism.

What are the two ways in which nervous system communicates with muscle?

Communication and control of the muscles cells takes place either through brain (voluntary actions) or through spinal cord (reflex action).

What two systems work together to protect the body from infection?

The acquired immune system, with help from the innate system, makes special proteins (called antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader.

What controls movement of muscles?

The movements your muscles make are coordinated and controlled by the brain and nervous system. The involuntary muscles are controlled by structures deep within the brain and the upper part of the spinal cord called the brain stem.

What part of spine controls legs?

Lumbar region

The lumbar spinal cord is the lower area of the back. Nerve roots coming from the spinal cord in the lumbar spine control the legs. The lumbar region is where the spinal cord ends (the spinal cord is shorter than the spine).

What part of the brain controls taste?

The gustatory cortex is the region of the brain responsible for processing taste. Gustation, or taste, is important in diet and pleasure. The gustatory cortex is composed of two parts on two different lobes. The anterior insula is located on the insular lobes and the frontal operculum is on the frontal lobe.

What are 3 major functions of the nervous system?

First, the basic functions of the nervous system are sensation, integration, and response.

What are major functions of the nervous system?

The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.

What are the 4 major functions of the nervous system?

It controls the voluntary and involuntary movement of the body. It maintains the balance of the body. It maintains the homeostasis of the body by doing functions such as thermal regulation, etc. It is responsible for sensing the stimuli, processing them, and sending the appropriate response.

Why is the brain stem so important?

It is responsible for many vital functions of life, such as breathing, consciousness, blood pressure, heart rate, and sleep. The brainstem contains many critical collections of white and grey matter. The grey matter within the brainstem consists of nerve cell bodies and forms many important brainstem nuclei.

Are there 3 main nervous systems of the body?

The nervous system includes the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord, whereas the PNS is made up of the somatic and autonomic nervous systems.

What organs make up the sensory system?

Much of this information comes through the sensory organs: the eyes, ears, nose, tongue, and skin. Specialized cells and tissues within these organs receive raw stimuli and translate them into signals the nervous system can use.

Does nervous mean scared?

(nɜːʳvəs ) 1. adjective [usually verb-link ADJECTIVE] If someone is nervous, they are frightened or worried about something that is happening or might happen, and show this in their behaviour.

What are nerves made of?

Your nerves are made up of: Axons, cord-like groups of fibers in the center of your nerve. Dendrites, branches that carry electrical impulses. Endoneurium, a layer of connective tissue surrounding axons.
