What else can I help you with?
Why during fight or flight do your muscles become tense?
During the fight or flight response, the body releases stress hormones like adrenaline, which increase muscle tension to prepare for a physical response. This increased muscle tension helps to improve strength and speed in either fighting or fleeing from a threat.
Which sensory receptor is sensitive to change in tension of a muscle?
proprioceptors
A thickening of existing muscle fibers is called?
Muscle hypertrophy is the thickening or increase in the size of existing muscle fibers. This process occurs in response to resistance training or overload, leading to an increase in muscle strength and size.
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 is the tension of muscle fibers called?
The tension of muscle fibers is called muscle tension. It refers to the force generated by a muscle when it contracts. Muscle tension is necessary for movement, posture, and stabilization of the body.
Why during fight or flight do your muscles become tense?
During the fight or flight response, the body releases stress hormones like adrenaline, which increase muscle tension to prepare for a physical response. This increased muscle tension helps to improve strength and speed in either fighting or fleeing from a threat.
Which sensory receptor is sensitive to change in tension of a muscle?
proprioceptors
A contraction in which there is no change in muscle length but there is a great increase in muscle tension is?
isometric contractions
How do muscle relaxants work to alleviate muscle tension and spasms?
Muscle relaxants work by targeting the central nervous system to reduce muscle contractions and increase blood flow to the affected area, which helps alleviate muscle tension and spasms.
What reflex causes muscles relaxation and lengthening in response to muscle tension?
The reflex of the Golgi tendon.
When a muscle is stimulated repeatedly at a high rate the amount of tension gradually increase to a steady maximum tension is?
complete tetanus
A contraction in which the muscle does not shorten but its tension increase is called isometric.true or false?
True Tension may build to the muscles peak tension capacity, but the muscle neither shortens or lengthens example. trying to lift a car
What contraction that shortens the muscle but does not increase tension is called?
It is called concentric isotonic contraction.
The first stage of the sexual response cycle is the?
The first stage of the sexual response cycle is the arousal stage, where there is an increase in blood flow to the genital area, muscle tension, and heart rate. This stage is typically triggered by physical or psychological stimuli.
A thickening of existing muscle fibers is called?
Muscle hypertrophy is the thickening or increase in the size of existing muscle fibers. This process occurs in response to resistance training or overload, leading to an increase in muscle strength and size.

What type of receptor detects muscle length?
Muscle Spindle
