What else can I help you with?
What are long fibers called?
Muscle cells are called fibers.
What are norepinephrine releasing fibers called?
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
In most animals axons and dendrites are clustered into bundles of fiber called?
In most animals, axons and dendrites are clustered into bundles of fibers called nerves or nerve fibers. These fibers are responsible for transmitting electrical signals throughout the body, allowing for communication between different parts of the nervous system.
What is the natural cluster of wool fibers called?
A natural cluster of wool fibers is called a fleece.
Fibers that connect two halves of the brain are called?
The fibers that connect the two halves of the brain are called the corpus callosum. It is a band of nerve fibers that allows communication and coordination between the left and right hemispheres of the brain.
Network that stimulates the myocardium into contraction?
His bundle? or the Purkinje fibers?
A single neuron and all the muscle fibers it stimulates comprise a?
This is called a motor unit.
What motor neuron and all the muscle fibers it innervates called?
the motor unit
How would a drug that stimulates acetylcholine receptors affect the sympathetic nervous system?
Preganglionic fibers for the SNS release ACh; so a drug that stimulates ACh receptors would stimulate the postganglionic fibers of sypathetic nerves, resulting in increased sympathetic activity
What fibers are the sweat glands innervated by?
Sweat glands are innervated by adrenergic sympathetic nerve fibers from the autonomic nervous system. These fibers release norepinephrine, which stimulates the sweat glands to produce sweat.
What are long fibers called?
Muscle cells are called fibers.
How does a piece of paper absorb water?
Paper is made from fibers such as cellulose, which have many tiny spaces between them. When water comes into contact with paper, these spaces act like small capillaries, allowing the water to be drawn into the paper through a process called capillary action, where water moves due to the forces between the water and the cellulose fibers.
What are the fibers connecting the to hemisphere?
The fibers connecting the two hemispheres of the brain are called the corpus callosum. It is a thick band of nerve fibers that allows communication and information transfer between the left and right hemispheres.
What stimulates the adrenal medulla to secrete its excitatory hormones?
preganglionic sympathetic fibers releasing acetylcholine that bind to receptors on the adrenal medulla
Which part of the intrinsic conduction system sends fibers along the lateral walls of the ventricles towards the base and stimulates the papillary muscles?
The moderator band, also known as the septomarginal trabecula, sends fibers along the lateral walls of the ventricles towards the base and stimulates the papillary muscles. It helps coordinate the contractions of the ventricular walls and the papillary muscles to facilitate proper valve function.
What are norepinephrine releasing fibers called?
Andrenergic fibers release Norepinephrine and Cholinergic fibers release Acetylcholine.
How a light touch stimulates a nerve impulse?
A light touch stimulates a nerve impulse by activating sensory receptors in the skin called mechanoreceptors. These receptors detect mechanical deformation or pressure caused by the touch, which then triggers an electrical signal to be sent along the nerve fibers to the brain for processing. The brain interprets this signal as a sensation of touch.
