What are the 2 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 effectors in the nervous system?
Muscles and glands are called effectors because they cause an effect in response to directions from the nervous system. This is the motor output or motor function.
What are the 3 types of effectors?
Examples of effectors are as follows: (1) allosteric effectors, (2) bacterial effectors, and (3) fungal effectors (e.g. apoplastic effectors and cytoplasmic effectors). In other biological contexts, the term effector is used to describe an organ, a gland, or a muscle that responds to a nerve impulse.
What are the 2 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 effector response?
effector cell, type of cell in the body that carries out a specific activity in response to stimulation. … The production of effector cells in response to first-time exposure to an antigen is called the primary immune response.
Is the sensory neuron an effector?
The primary components of the reflex arc are the sensory neurons (or receptors) that receive stimulation and in turn connect to other nerve cells that activate muscle cells (or effectors), which perform the reflex action.
What are the effectors in the eye?
The eye responds to bright light to protect the retina from damageThe bright light triggers a reflex that makes the pupils smaller, meaning less light enters the eyeAs with all reflexes, there is a stimulus, receptor and effectorThe stimulus is the light, the receptor is the light receptors in the eye and the effectors …
What are the two divisions 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.
Which of the following are examples of an effector?
Effectors include muscles and glands – that produce a specific response to a detected stimulus. a muscle contracting to move an arm. muscle squeezing saliva from the salivary gland. a gland releasing a hormone into the blood.
Is a motor neuron an effector?
A motor neuron transmits impulses from a central area of the nervous system to an effector, such as a muscle.
What is an effector What are two types of effectors quizlet?
What are two types of effectors? An effector causes an effect in response to directions from the nervous system. Types include muscles and glands.
Is the heart an effector?
An effector is a tissue structure, namely a muscle or gland, that responds to an efferent impulse. … The third and final type of muscle is cardiac muscle, also under involuntary control. Cardiac muscle fibers (muscle cells) comprise the heart (‘cardia-‘).
