…senses the stimulus, and the affector, the nerve cell that directly activates the muscle. These are a theoretical minimum rather than an observed functional arrangement of cells in the body of an animal (see instinct: Varieties of instinctive behaviour).

sensory neurons in the shoulder to the spinal cord and onto the brain until Polysynaptic reflex arc: involving interneurons connecting the affector and effector.

In its most primitive form, a nerve net consists only of affector neurons and effector neurons, i.e. it has no association neurons, but it is doubtful whether such a primitive nerve net is to be found in any animal living at present. 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. Source for information on effector neuron: A Dictionary of Biology dictionary.

that can respond to a stimulus from a nerve. these have one or more receptors that detect change in either the external or internal environment, information that is detected is transmitted as an electrical impulse to the CNS by the affector The preganglionic neurons originate in the brain stem or sacral spinal cord and are relatively long. The preganglionic neurons synapse with postganglionic neurons in ganglia near the effector organ or in the wall of the effector organ.: Cranial nerve nuclei are in the brainstem and travel with cranial nerves III, … 2021-01-26 (iii) The central nervous system consists of the brain and the spinal cord. (iv) Motor neurons carry impulses from the CNS to effector organs. They are also called efferent neurons. (v) Effectors are muscles or glands which work in response to the stimulus received from the motor neurons. The motor neuron is present in the grey matter of the spinal cord and medulla oblongata, and forms an electrochemical pathway to the effector organ or muscle.

Axon, cell body, dendrite, myelin sheath, node of Ranvier,. Functions: coordinate/ control. Reflex arc - receptor, affector/sensory, interneurons, effector/motor,.

Afferent and efferent neurons are two major types of neurons present in the nervous system. Afferent neurons bring nerve impulses generated by the sensory organs to the central nervous system. Receptors of the sensory organs receive external stimuli and generate into nerve impulses and send to the brain and spinal cord by the afferent neurons, which are sensory neurons.

Which best represents the path of an impulse over a reflex arc?

2018-06-08 · Peripheral tissue at the outer end of an efferent neural path (one leading away from the central nervous system). An effector acts in special ways in response to a nerve impulse.
Recruitive

From: effector neuron in A Dictionary of Biology ». Now, some nerves will carry this information to the central nervous system i.e. spinal cord in this case, so these nerves will be afferent neurons and the nerves which carry back the information of action will be efferent nerves.

Largest part of the mammalian brain, divided into two side and connected by thick bands of nerves. Dendrites. Extentions of the nerve cell in which impulses are transmitted to that cell. Effector Neurons. The type of neuron that sends information from the central nervous system to muscle cells or glands.

Their effectors and affectors are therefore not located in the same organ. In the distal end of the tibialis anterior muscle lie the effectors of reflex movement. Effector (noun) one who brings about a result or event; one who accomplishes a purpose. Effector (noun) a nerve fiber that terminates on a muscle or gland and stimulates contraction or secretion. Effector (noun) an organ (a gland or muscle) that becomes active in response to nerve impulses. Princeton's WordNet. • Interneurons connect neurons within specific regions of the central nervous system.
