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.
What else can I help you with?
The two neurotransmitters that affect smooth muscle cells are acetylcholine and?
norepinephrine. Acetylcholine mainly causes smooth muscle contraction, while norepinephrine can either cause contraction or relaxation depending on the type of receptor it binds to on the smooth muscle cell.
What can acetylcholine and norepinephrine affect?
Smooth Muscle Cells
is a neurotransmitter vasoconstrictor and smooth muscle stimulant?
Yes, certain neurotransmitters can act as vasoconstrictors and stimulate smooth muscle. For example, norepinephrine primarily released from sympathetic nerve endings can cause vasoconstriction by binding to alpha-adrenergic receptors on smooth muscle cells in blood vessels. This action leads to increased vascular resistance and reduced blood flow to certain areas. Other neurotransmitters, such as angiotensin II, also have similar effects on smooth muscle contraction and vasoconstriction.
Which type of muscles contain spindle shaped cells?
Skeletal muscle tissue has cylindrical cells. Due to the cells in the skeletal muscle, the muscle can now allow movement to the bones in the body.
Is smooth muscle cells voluntary?
no, skeletal muscle cells are
How are smooth muscle cells similar to skeletal fibers?
Smooth muscle cells are similar to skeletal muscle cells due to the actin-tropomyosin interactions. These interactions "tell" the muscle when to contract.
What best describes the cells of unitary smooth muscle?
Smooth muscle is the involuntarily controlled muscle. In unitary smooth muscle, the cells are connected by gap junctions and are controlled by the autonomic nervous system and hormones.
Which tissues are mainly responsible for vasoconstriction?
Smooth muscle cells within the walls of blood vessels are mainly responsible for vasoconstriction. When stimulated by various factors such as hormones or neurotransmitters, these smooth muscle cells contract, narrowing the diameter of the blood vessel and increasing vascular resistance. This process helps regulate blood flow and blood pressure in the body.
Which of these cells are likely to have multiple nuclei skeletal muscle cardiac muscle smooth muscle or neuron?
skeletal smooth muscle neuron
What muscle tissue spindle-shape cells?
Smooth Muscle
Do smooth muscles have branched cells?
No, cardiac muscle cells are branched but skeletal muscle cells are linear and do not branch
Do smooth muscle cells posses central nuclei but lack striations?
Smooth muscle is not striated, hence the name smooth muscle.nonotcardiac muscle
