No, a receptor is not a muscle's automatic response; rather, it is a specialized structure that detects specific stimuli in the environment, such as light, sound, or touch. When receptors are activated, they send signals to the nervous system, which can then initiate an automatic response, such as a muscle contraction. This process involves multiple steps, including sensory input, processing in the brain or spinal cord, and motor output.

What is the name of pathway of neurones that impulses in an automatic response follow?
The pathway of neurons that impulses in an automatic response follow is called the reflex arc. This involves sensory neurons detecting a stimulus, sending a signal to the spinal cord, which then processes the information and sends a response via motor neurons back to the muscles or glands.
Where are the receptor sights located for kinesthetic sense?
It depends on what the receptor cells are for. If they are for vision, they are located in the retina of the eye. If they are for hearing, they are located in the organ of Corti, and so on and so forth.
Which vessels vasoconstrict in response to epinephrine and norepinephrine?
Epinephrine and norepinephrine primarily cause vasoconstriction in the small blood vessels of the skin, gastrointestinal tract, and kidneys through their action on alpha-1 adrenergic receptors. This response helps redirect blood flow to vital organs and muscles during a fight-or-flight situation. In contrast, in skeletal muscle, epinephrine can also cause vasodilation via beta-2 adrenergic receptors, depending on the context. Overall, the net effect varies based on receptor subtype distribution and the physiological situation.
What type of receptor fires in response to an increase in muscle tension?
The type of receptor that fires in response to an increase in muscle tension is called a Golgi tendon organ (GTO). These receptors are located at the junction of muscles and tendons and are sensitive to changes in muscle tension and force. When muscle tension increases, the GTOs activate, sending signals to the central nervous system to help regulate muscle contraction and prevent injury. This feedback mechanism plays a crucial role in proprioception and motor control.
What are parts to a feedback loop a sensory receptors?
A feedback loop involving sensory receptors typically includes three main parts: the sensory receptor, the control center, and the effectors. The sensory receptor detects changes in the environment (stimuli) and sends this information to the control center, which processes the input and determines the appropriate response. The control center then signals the effectors (muscles or glands) to carry out the response, thereby regulating the body's reaction to the stimuli. This process helps maintain homeostasis and adapt to changes in the environment.

Receptor found in muscles provide information about length or change in length of skeletal muscles?
muscle spindle

What is a reflex pathway and what is its path?
A reflex pathway is a neural circuit that enables an automatic response to a stimulus without the need for conscious thought. It typically follows a specific path: the sensory receptor detects a stimulus, sends signals through sensory neurons to the spinal cord, where interneurons relay the information to motor neurons, which then activate the appropriate muscles or glands to produce a response. This rapid communication allows for quick reactions, often crucial for survival.

What are holes in the surface of the dendrites or certain cells of the muscles and glands that are shaped to fit only certain neurotransmitters?
Neurotransmitter receptor sites on ligand-gated ion pores.

The type of receptor that fires in response to an increase in muscle tension is called a Golgi tendon organ (GTO).

What is the response caused by spinal cord interpreting an impulse from sensory receptor?
The only response by the spinal cord is not an interpretation but a reflex. A sensory impulse comes in and at the cord a reflexive arc occurs taking information to muscles or glands. The brain does the interpretation. You touch a hot stove and that info goes to the spinal cord which causes a reflexive action where the muscles move the hand away. All that happens before the brain gets an "incident report".
What are parts to a feedback loop a sensory receptors?
A feedback loop involving sensory receptors typically includes three main parts: the sensory receptor, the control center, and the effectors. The sensory receptor detects changes in the environment (stimuli) and sends this information to the control center, which processes the input and determines the appropriate response. The control center then signals the effectors (muscles or glands) to carry out the response, thereby regulating the body's reaction to the stimuli. This process helps maintain homeostasis and adapt to changes in the environment.
How nerve impulsive are transmitted from the receptor to central nervous system to effectors?
Nerve impulses are transmitted from the receptor to the central nervous system via sensory neurons. In the central nervous system, the impulse is processed and may be relayed to motor neurons that carry the impulse to effectors such as muscles or glands to produce a response. This pathway allows for communication and coordination between different parts of the body.
Effectors of a reflex arc are glands and what?
Effectors of a reflex arc are primarily muscles and glands. Muscles are responsible for carrying out the response by contracting or relaxing, while glands may secrete hormones in response to the stimulus.
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.
