Quick Answer: Are examples of effectors of the nervous system?

What are the effectors of the nervous system?

Based on the sensory input and integration, the nervous system responds by sending signals to muscles, causing them to contract, or to glands, causing them to produce secretions. Muscles and glands are called effectors because they cause an effect in response to directions from the nervous system.

Are examples of effectors of the nervous system quizlet?

Give two examples of effectors. A receptor is sense organs and simple sensory nerve endings that go to the CNS. Two examples of effectors would be cells and organs. Distinguish between the central and peripheral nervous system, and between visceral and somatic divisions of the sensory and motor systems.

What are the two types of effectors in the nervous system?

1 .

Are the organs that perform the responses of the Nervous System. There are two types of effectors, the muscles (also called “motor effectors”) and exocrine glands (also called “secretory efectors”). All effectors are stimulated by nerves ie are “innervated”.

Are effectors part of the nervous system?

The Somatic Nervous System (SNS) includes all nerves controlling the muscular system and external sensory receptors. External sense organs (including skin) are receptors. Muscle fibers and gland cells are effectors. The reflex arc is an automatic, involuntary reaction to a stimulus.

What are the 3 types of effectors?

The muscles are generally divided into two groupings: somatic effectors, which are the body’s striated muscles (such as those found in the arm and back), and autonomic effectors, which are smooth muscles (such as the iris of the eye).

What are the two main subdivisions 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.

What makes up the nervous system quizlet?

What makes up the nervous system? Brain, spinal cord, nerves, and ganglia.

What is another name for the autonomic nervous system?

Another name for the autonomic nervous system is the visceral motor system.

What is an example of an effector organ?

Effectors are parts of the body – such as muscles and glands – that produce a response to a detected stimulus. For example: a muscle contracting to move an arm. muscle squeezing saliva from the salivary gland.

What is a receptor in the nervous system?

Receptors. Receptors are groups of specialised cells. They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond to specific stimuli.

What is the role of the central nervous system?

The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.

What are the two coordinators of the nervous system?

Information from receptors passes along neurones as electrical impulses to coordinators such as the central nervous system (CNS). The CNS is the brain and spinal cord. Muscles contracting or glands secreting hormones are the response of effectors coordinated by the CNS.

What is nervous system and its function?

The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).

Why nervous system is important?

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

What is nervous system in human body?

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.
