When a girl bends her arm, she uses a different muscle to bring it back to the original position. why can't she use the same mus
PilotLPTM [1.2K]
For the answer to the question above, <span>Muscles can only contract, not push </span>

<span>"Muscle fiber generates tension through the action of actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten or remain the same. Though the term 'contraction' implies shortening, when referring to the muscular system it means muscle fibers generating tension with the help of motor neurons (the terms twitch tension, twitch force, and fiber contraction are also used)."</span>

Research the name of the receptor of the five senses and describe how the receptor works.
tresset_1 [31]

Answer:

Photoreceptors - Eyes

Phono receptor - Ears

Olfactory receptors - Nose

Gustatory receptors - Tongue

Thermoreceptors - skin

Explanation:

Each receptor has sensory neurons at their tips. On receiving the information from the surrounding the start a nerve impulse. This is carried to the brain through the spinal cord. The information is transferred to different parts within the brain using relay neurons. After that, the response is again sent using nerve impulses, but this time through motor neurons. This information is passed to the effector where the response would be observed.
