Is heart just an organ or does it have nerve cells and its own responses and activities ? "Have they not travelled through the land, and have they hearts

Efferent nerve fibers are described as motor nerve fibers yes or no? Motor nerve-- Motor or efferent nerve cells carry impulses from the brain to muscle or organ tissue.

3) Efferent nerve fibers may be described as motor nerve fibers. T. 4) Cell bodies of sensory neurons may be located in ganglia lying outside the central nervous system. T. 5) Myelination of the nerve fibers in the central nervous system is the job of the oligodendrocyte. T an action potential, a wave of deplarization in a nerve cell, is the same as the (nerve impulse) true the same impulse will be generated in a nerve cell regardless of the size of the stimulus once the threshold has been reached.

Nerve impulses described as efferent are

Symptoms include In lower vertebrates the visceral efferent column of the cord is continued forward as a column in the brain constituting the nuclei of origin of the efferent roots of the X, IX, VII and V nerves. In fishes, where the voluminous musculature of the gill apparatus is to be innervated, this is a large and important column of gray matter at either side of the ventricle as far forward as the Efferent neurons are motor nerves These are motor neurons carrying neural impulses away from the central nervous system and toward muscles to cause movement. Efferent neurons send signals from the brain to the muscles, glands, and organs of the body in response to sensory input. Efferent nerve fibers refer to axonal projections that exit a particular region; as opposed to afferent projections that arrive at the region. These terms have a slightly different meaning in the context of the peripheral nervous system (PNS) and central nervous system (CNS). An axon or nerve fibre, is a long slender projection of a nerve cell that conducts electrical impulses away from the neuron's cell body or soma.

Spinal Nerves are described as___nerves because they carry both afferent and efferent signals. Mixed. Which ramus of a spinal nerve innervates the local muscles, Efferent neurons carry impulses away from the CNS. A quick contraction of flexor muscles in response to a painful stimulus is called a_reflex.

When an injury or medical condition affects the inner ear or the auditory nerve that as disturb the efferent system, noise will be more damaging to the inner ear in Impulse noise is known to cause more hearing loss than wide band noise. Sensory sensitisation describes a changed quality in sensory nerve pathways with hyperexcitability and facilitated transmission of nerve impulses to the sensory classifiable. classification.

Nerve impulses described as efferent are

True/False 1) Reflexes are rapid, automatic responses to stimuli. 2) Efferent nerve fibers may be described as motor nerve fibers. 3) Myelination of the nerve fibers in the central nervous system is the job of the oligodendrocyte. 4) During depolarization, the inside of the neuron's membrane becomes less negative.

Nerve include three types that are afferent nerves, efferent nerves, and mixed nerves; on the other side, neuron constitutes the types called sensory neurons, motor neurons, and interneurons.

Motor (efferent) neurons are bipolar. d.

Action potentials can travel along axons at speeds of 0.1-100 m/s. This means that nerve impulses can get from one part of a body to another in a few milliseconds, which allows for fast responses to stimuli.

T 2021-02-23 · Nerve fibers that travel to the tectum to regulate the pupillary light reflex are known as the pupillary afferent fibers.
