Answer:
Skeletal muscle fibre will contract to remove your hands instantly when you touch a hot object.
Explanation:
We take a step away from a heated object. This is related to sensitivity to stimuli. When we contact a hot object, our sensory organs detect the temperature and we remove our hand. The sensory neuron transports the stimulus to the brain, while motor neurons transport it back to the effector organs.
Reflex is a remarkable trait that evolution bestowed to us to aid in our survival. When a part of your body comes into contact with an object that could cause you damage, you tend to withdraw that part of your body rapidly. This occurs before your brain has had a chance to process the threat.
Reflexive Behavior
If you unintentionally touched a hot pot on your stove while cooking, you would grab your hand away from the pot reflexively (and virtually instantly). This is known as a reflex action.'
Arc of Reflex
Contact with the hot pot sets off a chain of events in the body that elicits a response.
Skin receptors swiftly send nerve impulses (electrical) to the spinal cord (central nervous system) when they come into touch with the hot pot. The impulses are processed in the spinal cord, and a reaction is given back.
Muscle fibres are made up of a single muscle cell. They assist in the management of physical forces within the body. They can facilitate organized movement of your limbs and tissues when gathered together.
Distinct forms of muscle tissue serve different purposes in your body:
- Muscle of the skeleton- Tendons connect these muscles to your bones, which control your voluntary motions. Walking, bending over, and picking up an object are among examples.
- A muscle that is smooth- Smooth muscles are involuntary, which means they cannot be controlled. They can be present in your internal organs as well as your eyes. Moving food through your digestive tract and adjusting the size of your pupils are two of their duties.
- The cardiac muscle- The cardiac muscle is located in the heart. It, too, is involuntary, like a smooth muscle. Cardiac muscle contracts in unison to allow your heart to beat.
