Skeletal muscle:
(occurs at neuro muscular junction)
At the end of the skeletal muscle fibre, there is a single motor neuron that forms many finer branches. At the end of these branches is a synaptic terminal which contain mitochondria and vesicles which in turn contain ACh.
So, when an action potential is propagated down towards the synaptic terminal, ACh is triggered to be released by exocytosis into the synaptic cleft and then onto the motor end plate (which is the other surface upon which the action potential will propagate; this is highly folded for increased surface area).
ACh then binds to receptors on the motor end plate, changing its permeability to Na+ ions. Na+ ions (due to an increased electrochemical gradient) rush into the sarcolemma. This influx increases until AChE breaks down the ACh. This influx results in the generation of an action potential!

What types of things are living things capable of responding to?
. . . of responding to stimuli.
What is the one characteristic that all sensory systems have in common?
All sensory systems share the function of detecting and responding to stimuli from the environment. They convert these stimuli into electrical signals that can be interpreted by the brain to generate a response.
Why would fungi decline after disappearance of insects?
because its responding to stimuli
Responding or adjusting to factors in the environment is what sign of life?
Response to stimuli.
What characterizes a person who is 'out of touch with reality'?
When a person is responding to non-existent stimuli (environment) and/or not responding to existent (present environment) stimuli. In other words, a person is interacting with 'something that is not there' or not interacting with their environment that is definitely present.
Responding to stimuli that are similar-but not identical-to a conditioned stimulus is call?
Responding to similar stimuli is known as generalization in classical conditioning. This occurs when an organism responds to a stimulus that is similar, but not identical, to the original conditioned stimulus that was paired with an unconditioned stimulus.
Which type of sensory receptor os responsible for responding to pressure?
Mechanoreceptors are responsible for responding to pressure. They detect mechanical stimuli such as pressure, vibration, and stretch in the body.
What is responding stimuli?
Response to stimuli refers to a response to outside stimuli such as a noise or a smell. It is a term that refers to an organisms ability to respond to the outside environment.
How does Aricept work?
One of the main problems in Alzheimers disease is a decrease in acetylcholine, a neurotransmittor. Aricept blocks an enzyme called acetylcholine esterase from breaking down acetylcholine so that the available neurotransmittor can work for a longer period of time.
What are the function of the nociceptors?
Detecting painful stimuli
Responding to stimuli that are similar but not identical to a conditioned stimulus is called?
Generalization. This occurs when an organism responds to stimuli that are similar to the original conditioned stimulus that was paired with the unconditioned stimulus.
What are passive smart materials?
Passive smart materials: which can only sense the environmental condition or stimuli. Active smart materials: which sense and react to the condition or stimuli. Very smart materials: which can sense, react and adapt themselves accordingly. Intelligent materials: which are those capable of responding or activated to perform a function in a manual or pre-programmed manner.
