What does the effector muscle do?
The effector is a muscle or gland that responds to an efferent impulse. An efferent impulse is a biochemical impulse, an electrical signal of sorts, which travels via nerve fibers away from the central nervous system. The response, the ultimate result of an action performed by an effector as a result of the stimulus.
What is the effector and what does it do?
Effectors are parts of the body – such as muscles and glands – that produce a response to a detected stimulus. For example: muscle squeezing saliva from the salivary gland. a gland releasing a hormone into the blood.
What does the effector do in 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 is the role of the effector organ in a reflex arc?
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 is the role of the effector in homeostasis?
An effector is any organ or tissue that receives information from the integrating center and acts to bring about the changes needed to maintain homeostasis. One example is the kidney, which retains water if blood pressure is too low.
What is the role of dendrites?
The Dendrites Dendrites are appendages that are designed to receive communications from other cells. They resemble a tree-like structure, forming projections that become stimulated by other neurons and conduct the electrochemical charge to the cell body (or, more rarely, directly to the axons).
What is the function of effector neuron?
effector neuron A nerve cell, such as a motor neuron, that transmits impulses from the central nervous system to an effector in order to bring about a physiological response to changes in the environment.
How are the effectors ( or muscles ) or muscles cause action or movement?
When a motor nerve impulse sent by the spinal cord (or brain) reaches the effector organs (which are muscles), then the muscles cause action or movement (such as lifting the hand away from a hot plate). We will now describe how muscles are able to move in response to electrical nerve impulses and cause action.
What kind of muscle responds to an efferent impulse?
An effector is a tissue structure, namely a muscle or gland, that responds to an efferent impulse. An efferent impulse is a biochemical and electrical impulse that travels via nerve fibers away from the central nervous system. The central nervous system is a term for the brain and spinal cord.
How does an effector respond to an efferent impulse?
The effector is a muscle or gland that responds to an efferent impulse. An efferent impulse is a biochemical impulse, an electrical signal of sorts, which travels via nerve fibers away from the central nervous system. 5. The response, the ultimate result of an action performed by an effector as a result of the stimulus.
Which is the role of the effector in the brain?
1. A stimulus is something that starts, stops, or changes a response. 2. The receptor is the site where the stimulus occurs and/or is sensed. 3. The coordinator is the central nervous system, which is the brain and spinal cord. 4. The effector is a muscle or gland that responds to an efferent impulse.
