When legs muscles respond to stimulus by moving the foot the response depends most directly on the functioning of?
Nerves
How does a stimulus create a response?
A stimulus triggers a signal in sensory receptors, which is then transmitted through the nervous system to the brain. The brain processes this signal and initiates a response by sending signals to the appropriate muscles or glands to react to the stimulus.
Which type of smiling occurs as a response to an external stimulus?
Duchenne smiling occurs as a response to an external stimulus. It involves the activation of both the mouth muscles (raising the corners of the mouth) and the eye muscles, creating genuine or spontaneous smiles.
The response of an effector is?
The response of an effector is the action or change that it produces in response to a stimulus. Effectors are organs or structures in the body that carry out the response, such as muscles contracting in response to a nerve signal. This response helps to bring about homeostasis and maintain the body's internal balance.
What are muscles or glands that bring about a coordinated response?
Effectors are muscles or glands that bring about a coordinated response in reaction to a stimulus. They execute the commands sent by the central nervous system to produce movements or secretions in response to a specific signal.
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.
What is an example of a stimulus and a possible response in humans?
For e.g. perception is a complex process of response to stimuli..when cat sees(stimulus) that we are moving towards her she gets scared and runs away(response). Or when rain starts(stimulus) we suddenly wants to hide ourselves from umbrella or by other means(response).
What are your body's response to stimuli coordinated by?
Your body's response to stimuli is coordinated by the nervous system. When a stimulus is detected by sensory receptors, the information is transmitted to the brain and spinal cord for processing. The nervous system then sends signals to muscles, glands, or other parts of the body to respond appropriately to the stimulus.
What is responsible for reflex action?
Reflex actions are controlled by the spinal cord and do not involve the brain. When a stimulus is detected, a signal is sent to the spinal cord, which then triggers a quick response from the muscles to react to the stimulus without conscious thought.
What is a motor response?
A motor response is the physical reaction of an organism to a stimulus, typically involving movement or activity of muscles. It can be voluntary, such as deciding to move your hand, or involuntary, like a reflex action that occurs automatically in response to a stimulus. Motor responses are essential for interacting with the environment and can be influenced by various factors, including the nervous system and muscle coordination.
What is the chain of events for a conscious response starting with stimulus?
A stimulus is perceived by sensory receptors, which then send signals to the brain through the nervous system. The brain processes the information and formulates a response, which is sent back through the nervous system to muscles or glands for action. The response is then carried out, leading to a conscious reaction to the original stimulus.
What does the all or none response mean dealing with muscles?
The All or None Muscle Theory is a theory that states that if said muscle is contracted, all of said muscle is contracted. In Essentials of Strength Training and Conditioning written by CSCS, they state,"There is no such thing as a motor neuron stimulus that causes only some of the fibers to contract."
