Afferent neurons transmit sensory information from peripheral receptors to the central nervous system (CNS), typically in the form of action potentials generated by stimuli like touch, temperature, or pain. Efferent neurons, on the other hand, convey motor commands from the CNS to effectors, such as muscles and glands, also using action potentials. Both types of neurons communicate through synapses, where neurotransmitters facilitate the transfer of signals.
What else can I help you with?
Explain how the blood vessels associated with the renal corpuscle help to maintain a relatively high blood pressure within the glomerulus?
The cluster of capillaries that forms a glomerulus arises from an afferent arteriole. After passing through the glomerular capillaries, blood (minus any filtered fluid) enters an efferent arteriole whose diameter is smaller than that of the afferent vessel. This is instead of entering a venule, the usual circulatory route. The efferent arteriole resists blood flow to some extent, which backs up blood into the glomerulus, increasing pressure in the glomerular capillary.
In general neural messages are received by the and transmitted by the?
In general, neural messages are received by the dendrites of a neuron and transmitted by the axon. Dendrites are specialized structures that detect signals from other neurons, while the axon carries electrical impulses away from the neuron's cell body to communicate with other neurons or target tissues. This process forms the basis of neural communication within the nervous system.
What are the cell that forms nervous tissue called?
neurons (which trasmit impulses) and glial cells which provide support and nutrition for the neurons.
What are the different forms called in an element that has forms with different numbers of neurons?
An element that has forms with different numbers of neurons is referred to as an "allotrope." Allotropes are different forms of the same element that have distinct physical or chemical properties due to variations in their atomic structure, such as differences in the number of neurons. Examples include carbon allotropes like graphite, diamond, and fullerene.
Do The neurons transfers information in the forms of an electrical impulse?
yes they do
What forms synapses or junctions with other neurons or effector cells?
axon terminals
What are relay neurons?
An interneuron (also called relay neuron, association neuron, connector neuron or local circuit neuron) is a neuron that forms a connection between other neurons. Interneurons are neither motor nor sensory.
Do neurons hold the same genetic information as somatic cells?
No, there is not any information that neurons hold the same genetic information as somatic cells. Somatic cells are the biological form of an animal, neurons are the forms of elements not organisms.
What is formed by the union of a cranial and a spinal root?
The union of a cranial and a spinal root forms a mixed spinal nerve. This nerve contains both sensory (afferent) fibers, which carry information from the body to the central nervous system, and motor (efferent) fibers, which transmit signals from the central nervous system to muscles. The mixed spinal nerve branches out to supply various parts of the body, facilitating communication between the nervous system and peripheral structures.
Is a association neuron unipolar?
No.Association neurons, or interneurons, connect 2 or more neurons and therefore are bipolar or multipolar. An example is the unipolar (or pseudounipolar) sensory neuron that connects, or forms a synapse, with a dorsal horn neuron which is an interneuron that connects with another neuron in the brainstem, i.e. in the geniculate or cuneate nuclei. Interneurons provide a point where information can be modulated, i.e. a stimulus can be excited or inhibited by input from other neurons.Unipolar neuron cell bodies are located in the dorsal root ganglia that receive afferent information from the periphery and transmit that information to the dorsal horn of the spinal cord. Because most authors report these neurons do not truly have only one process, but have a fused central and peripheral process, they are often referred to as pseudounipolar.
What germ layer does peripherial ganglion derive form?
If you are referring to the dorsal root ganglion, which is the major sensory ganglion for afferent cells. It also forms the peripheral ganglia.
What Is energy sent out as particles or waves?
Energy can be transmitted as both particles and waves. For instance, light energy is transmitted in waves, while heat energy can be transmitted through particles. These forms of energy help transfer energy from one place to another.
