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.
What is the system's reaction to the stimulus?
Stimulus detected by receptors, transmitted to brain via afferent neurones, info processed at brain, efferent neurones, then to affector such as muscles.
Which of these parts receive nerve impulses?
dendrites receive electrical and chemical signals from axon terminals.
What receptors in the ear detect changes in body position?
Proprioceptors in joints, tendons, etc. send signals to the cerebellum where the information is processed at a subconscious level. Signals also go to the cerebral cortex for processing at a conscious level
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
The receptors lying in joint and muscles are?
receptors lying in joint and muscles
What is the function of kinesthetic receptors?
The receptors for kinesthesis are nerve endings found in the parts of the body.
What happens when acetylcholine receptors are blocked?
There are several compounds and drugs that may block acetylcholine receptors. They are collectively known as cholinergic antagonists.
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.
What is the difference between feel and sense?
There are many sense organs in the body like touch receptors, pressure receptors, heart receptors, taste receptors, sound receptors, etc. All these receptors when stimulated result in changes in tone or isometric contraction of skeletal muscles around them or in the entire body.Sensation:Sensation is the observation of change in tone of skeletal muscles induced by a single sense organ.Thus, heat, sound, etc are sensations.Feeling:Feeling is the observation of changes in tone of skeletal muscles induced by many sense organs or continuous changes in a single sense organ.Thus, coffee induces a feeling and so does a song.
What action does the femoral nerve do?
Nerves do not have actions. Muscles do, but nerves go to certain receptors. The femoral nerve is the largest in the lumbar plexus and divides into many branches, and supplies the thigh muscles and leg and skin cutaneous receptors (feeling).
Muscles or glands that bring about a coordinated response?
Effectors is the term used for glands or muscles that result in a coordinated response. Receptors are what receive stimuli from the outside environment.
What is the other name for skeleton muscle?
Proprioceptors, stretch-reflex receptors.
Can you get a brain ache?
There are no pain receptors in your brain, so it feels no pain.
Receptors in the muscles tendons and joints that inform the brain of the position and movements of the body parts are functionally known as?
proprioreceptors
Why do hurt?
Due to the presence of lactic acid in your muscles, which triggers pain receptors in that area, causing the feeling of pain
What is the peripheral nevorus system?
It is located outside of the central nervous system and consists of nerves and sensory receptors, it carries impulses formed by receptors, such as pain and sound receptors, to the CNS and it carries impulses from the CNS to effectors, glands and muscles that carry out actions directed by the CNS
