No, a receptor is not a muscle. Receptors are specialized proteins or cells that detect and respond to specific stimuli, such as light, sound, or chemical signals. They play a crucial role in sensory perception and cellular communication, whereas muscles are tissues that contract to produce movement.

What is the difference between a stimulus impulse receptor and effector?
A Receptor is referring to a sense organ, like a nerve ending. An Effector is referring to a muscle capable of reflecting to a stimulus. By definition, receptor and effector are antonyms.
Relationship between agonist and antagonist?
An agonist is a drug or chemical that binds to a receptor and activates it, producing a biological response. In contrast, an antagonist is a substance that binds to a receptor but does not activate it, thereby blocking the receptor from being activated by other molecules. Agonists and antagonists often have opposite effects on a physiological process or pathway.
What happens when acetycholine binds to its receptor in the sarcolemma and triggers?
When acetylcholine binds to its receptor in the sarcolemma of a muscle cell, it triggers an action potential to be generated along the muscle cell membrane. This action potential then spreads along the sarcolemma and eventually leads to muscle contraction by initiating the release of calcium ions from the sarcoplasmic reticulum.
What is The Intersection Between A Neuron And Another Neuron A Muscle A Gland Or A Sensory Receptor?
The intersection between a neuron and another neuron, a muscle, a gland, or a sensory receptor is called a synapse. At this junction, the transmitting neuron releases neurotransmitters that bind to receptors on the receiving cell, which can be another neuron, a muscle cell (causing contraction), a gland (triggering secretion), or a sensory receptor (initiating sensory processing). This communication is crucial for nervous system function, allowing for the integration of signals and responses throughout the body.
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 type of receptor detects muscle length?
Muscle Spindle
Which neurotransmitter receptor is present on the sarcolemma?
Acetylcholine receptor is present on the sarcolemma of the muscle cells. This receptor is responsible for transmitting the signal to initiate muscle contraction when acetylcholine binds to it at the neuromuscular junction.
What is the difference between a stimulus impulse receptor and effector?
A Receptor is referring to a sense organ, like a nerve ending. An Effector is referring to a muscle capable of reflecting to a stimulus. By definition, receptor and effector are antonyms.
What is the pathway of an impulse in a reflex arc?
Sensory receptor, sensory neuron, interneuron, motor neuron, and muscle.

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

What is the receptor effector and stimulus?
Stimulus is like the cause of something or the theme. The receptor is what you use fir the stimulus e.g you look at a tv guide ( stimulus) and the receptor is your eyes because you use them to see it. The effector is the muscle used To use the tv guide so this could be your hand
Which sensory receptor is sensitive to change in tension of a muscle?
proprioceptors
What is a type of receptor that responds to changes in stretch of skeletal muscle and initiates a stretch reflex?
Muscle spindle receptors which are located in the belly's of muscles measure length of stretch and speed of change. They send this afferent neural information to the posterior horn of the spinal cord where and interneuron interprets the information and if the stretch is ballistic (if it changes length too rapidly) it will trigger an efferent motor unit, or many motor units, through the anterior horn of the spinal cord to contract the muscle.
