All of these neurons release acetylcholine as a neurotransmitter except?
specific cardiac and smooth muscle fibers
What Neurotransmitter diffuses across a synapse to a muscle cell?
It varies: In the somatic system (skeletal muscle) and parasympathetic branch of the autonomous nervous system (smooth & cardiac muscle) it is usually acetylcholine. In the sympathetic branch of the autonomous nervous system (smooth & cardiac muscle) it is usually norepinephrine (also called noradrenaline). There are exceptions, but this is the general rule.
What is the muscle that is found in the small intestine?
smooth musclesmooth muscle
Is an ulcer a cardiac muscle or a smooth muscle?
Smooth muscle
Which muscle tissue is involuntary and not striated?
SmoothI'm POSITIVE it's the Skeletal Muscle!
Is voluntary muscle smooth muscle?
yes it is.....
Is muscle cell is smooth when hungry?
No, "smooth" muscle is a type of muscle.
What is the neurotransmitter that initiates muscle contraction?
Voluntary muscle contraction is controlled by the central nervous system. The brain sends signals, in the form of action potentials, through the nervous system to the motor neuron that innervates several muscle fibers.Acetylcholine (ACh) is commonly secreted at neuromuscular junctions, the gaps between motor neurons and muscle cells, where it stimulates muscles to contract (by opening gated positive ion channels).
What are the two neurotransmitters that affect smooth muscle cells?
The main neurotransmitters involved with smooth muscle is Acetylcholine which causes an exited effect in smooth tissue and Adrenalin which causes an inhibitory effect. Adrenalin is produced by the adrenal gland when animals are in high stress or phsically elated situations. This causes the "flight or fight" mode in animals and increases function of regions of body necessary for survial such as skeletal muscle. Thus smooth muscle in the gut for example isn't vital in dangers situations therefore contraction of this muscle is decreased by the neurotransmitter.
Do smooth muscle cells posses central nuclei but lack striations?
Smooth muscle is not striated, hence the name smooth muscle.nonotcardiac muscle
Detrusor muscle what are the 3 layers?
Outer = longitudinal smooth muscle Middle= circular smooth muscle Innermost= longitudinal smooth muscle
What type of muscle is found in the wall of the stomach?
smooth muscle tissue. it is an involuntary muscle and the stomach can be controled by you.
