In the central nervous system (CNS), there are two main types of neuron fibers: afferent (sensory) fibers that carry information from sensory receptors to the CNS, and efferent (motor) fibers that carry information from the CNS to effectors such as muscles and glands. These fibers make up the vast network of connections that allow for communication within the brain and spinal cord.
What else can I help you with?
Which neuron delivers sensations to the cns?
Afferent neurons receive and transmit impulses to the CNS.
Where does each neuron in the CNS receive its input?
Each neuron in the CNS receives input from other neurons through synapses, which are specialized junctions where signals are transmitted from one neuron to another. These synapses can be excitatory or inhibitory, meaning they either increase or decrease the likelihood of the receiving neuron firing an action potential.
What are the most common neuron in cns?
multipolar, ya dingus.
Is myelination of the nerve fibers in the periphreal nervous system the job of the schwann cell?
Yes, Schwann cells are responsible for myelinating nerve fibers in the peripheral nervous system. They wrap around the axon of the neuron, creating a myelin sheath that helps to increase the speed at which nerve impulses travel along the neuron.
What are bundles of fibers that connect the CNS with the rest of the body?
Bundles of fibres running between the Central Nervous System (CNS) and all the tissues of the body are called Nerves. These nerves make up the Peripheral Nervous System (PNS). The correct name for the fibres in these bundles is Axons which are the long part of neuron cells carrying the signal from the cell body to the Target Tissue.
Do schwann cells wrap their cytoplasmic extensions around thick neuron fibers in the CNS?
NO they wrap around the axon in the PNS!
What is the difference between nerve and neuron?
A neuron is an individual cell in the PNS or CNS that can be excited and conduct impulses along its axon. A nerve is a bundle of multiple neuron fibers that each are carrying their own signals. They are protected by connective tissue. Eventually the neuron fibers diverge away from the nerve to reach their destination.
What is the job of his motor neurons?
controls musclesRelay messages from the Brain in the CNS down through the Spinal Cord and into the PNS, from there the motor neuron synapses on muscle fibers. i.e. knee jerk reflex & the neuromuscular junction.
Which neuron delivers sensations to the cns?
Afferent neurons receive and transmit impulses to the CNS.
Where neuron meets neuron?
they meet in the cns or relay naurone
What is a motor neuron attached to?
A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
Where does each neuron in the CNS receive its input?
Each neuron in the CNS receives input from other neurons through synapses, which are specialized junctions where signals are transmitted from one neuron to another. These synapses can be excitatory or inhibitory, meaning they either increase or decrease the likelihood of the receiving neuron firing an action potential.
Neuron that conducts impulses away from CNS to muscles and glands?
Efferent Neuron
Which type of neuron transfers messages across the CNS?
relay neuron
What are the most common neuron in cns?
multipolar, ya dingus.
What types of neuron carries impulses away from the CNS?
Motorneurons
Does a sensory neuron transmit afferent impulses to the cns?
True
