How are sound receptors stimulated?
Pain receptors are bare dendrites that react to a certain type of stimulus. Some pain receptors become activated when extremes of heat or cold cause your skin temperature to rise or fall to dangerous levels. Hope this helps!
What part of the cell is stimulated by outside chemicals triggering the cell to carry out specific functions?
Cell surface receptors are stimulated by outside chemicals, such as hormones or neurotransmitters, which in turn trigger the cell to carry out specific functions. The binding of these chemicals to the receptors initiates a signaling cascade within the cell that leads to various cellular responses.
The process by which the brain causes a sensation to seem to come from the stimulated receptors is called?
The process by which the brain causes a sensation to seem to come from the stimulated receptors is called sensory localization. This involves the brain integrating sensory information from different receptors to create a coherent perception of the world around us, including determining the location of the source of a sensation.
What occurs when beta receptors are stimulated?
Stimulation of beta receptors leads to increased heart rate, relaxation of bronchial smooth muscle, and release of glucose from the liver. This can result in increased blood flow to muscles, improved airway function, and a boost in energy levels to support physical activity.
Which type of receptor is stimulated by changes in pressure?
Mechanoreceptors are stimulated by changes in pressure or movements of body fluidsSourceIntroduction to the Human Bodyby Gerard Tortora and Bryan Derrickson
The neurotransmitter used at cholinergic synapse is?
The neurotransmitter is called acetylcholine. Cholinergic receptors are of two kinds: nicotinic receptors, which are situated in striated muscles and muscarinic receptors, which are situated in parasympathetically innervated structures.
Does sweat glands contain cholinergic receptors?
All the post-ganglionic parasympathatic reseptors are cholinergic (muscarinic) . and all the post-ganglionic sympaythatic reseptors are adrenergic . Except for sweat glands , Piloerecter muscles , and a few blood vessels they use sympathatic nerves but a cholinergic resepotrs . -Note that all the pre-ganglionic ( sympathatic and para sympathatic ) reseptors are cholinergic ( Nicotinic ). -Note that the sweat glands on the palms of the hand are adrenergic , but the rest of the sweat glands are cholinergic.
Receptors stimulated by changes in temperature?
Thermoreceptors
What receptors are stimulated when their hairs are bent?
Mechanoreceptors
What receptors are stimulated during urination?
Nerve receptors are stimulated during urination. This stimulation occurs when the walls of the bladder contract and the urination reflex is automatically activated.
What happens when the receptors in the skin are stimulated?
skin infection
What are the two types of catecholamines?
alpha receptors make the heart beat faster, the pupils of the eyes dilate, and the muscles contract. The beta receptors have similar effects and also cause the bronchi in the lungs to open up
Which is the first structure stimulated in a reflex arc?
Sensory receptors.
How come the stimulation of sweat secretion is carried out by sympathetic system by MUSCARINIC RECEPTORS as said in your table eventhough they are pararsympathetic cholinergic receptors?
All the post-ganglionic parasympathatic reseptors are cholinergic (muscarinic) . and all the post-ganglionic sympaythatic reseptors are adrenergic . Except for sweat glands , Piloerecter muscles , and a few blood vessels they use sympathatic nerves but a cholinergic resepotrs . -Note that all the pre-ganglionic ( sympathatic and para sympathatic ) reseptors are cholinergic ( Nicotinic ). -Note that the sweat glands on the palms of the hand are adrenergic , but the rest of the sweat glands are cholinergic.
What is the difference between direct acting and indirect acting cholinergic drugs?
Direct acting cholinergic drugs directly bind to and activate cholinergic receptors, while indirect acting cholinergic drugs increase cholinergic activity by inhibiting the enzyme acetylcholinesterase, which breaks down acetylcholine. Direct acting drugs include bethanechol and pilocarpine, while indirect acting drugs include donepezil and physostigmine.
Why Phenylephrine cause mydriasis but not cycloplegia?
Phenylephrine is an alpha one adrenergic receptor agonist. The radial muscles of the iris are innervated by neurons with alpha one receptors thus it causes dilation when stimulated. However the ciliary body of the eye (which controls accommodation) is controlled by muscarinic 3 cholinergic receptors. That pathway for accommodation remains unaffected while the iris is dilated so you will not get cycloplegia.
The two types of receptors that bind acetylcholine are?
nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotinemuscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.Nicotinic and muscarinic are two main kinds of "cholinergic" receptors.
