What is a stimulus that results in no perceptible contraction?
A subthreshold stimulus is one that does not generate a strong enough signal to elicit a perceptible contraction in muscle fibers. It is below the threshold required to cause an action potential and result in muscle contraction.
What change in an organism's surroundings that will cause the organism to react is called a?
Stimuli are things in the environment that cause change. A reaction to a change in the environment is a reaction to a stimulus.
What does Lower temperatures cause rocks to?
contract
Tissue has elongated cells that shorten and cause movement?
Muscle tissue is made up of elongated cells called muscle fibers that can contract and relax to produce movement. These muscle fibers contain specialized proteins that allow them to shorten and generate force, leading to various types of movements in the body.
What are functions of synaptic junction?
To "connect" two neurons, (or a neuron and a muscle cell), by providing a space between an axon terminal of one neuron and a dendrite of another neuron (or a muscle cell), so neurotransmitters that are released by an axon terminal can diffuse across that space to reach the dendrite (or muscle cell) and either initiate the possibility of the second neuron to fire or cause a muscle cell to contract.
How does the threshold stimulus influence muscle contraction?
The threshold stimulus is the stimulus required to create an action potential. So any stimulus under this level will not cause muscle contraction, while a stimulus above this level will cause the muscle to contract. The higher the stimulus the more muscle fibers are recruited, and thus the higher the response.
How does the stretch reflex cause the quadriceps femoris muscle group to contract?
Tapping on the patellar tendon stretches receptors called the muscle spindles in the quadriceps muscle group of the anterior thigh. This stimulus evokes a rapid motor reflex to contract the quadriceps and shorten the muscles. This process is called the patellar reflex.
What is the minimal level of stimulus to cause a muscle contraction?
it is known as the threshold stimulus usually seen in tonic contraction
What is the muscle's role in the body?
to contract to cause movement.
What is a stimulus that results in no perceptible contraction?
A subthreshold stimulus is one that does not generate a strong enough signal to elicit a perceptible contraction in muscle fibers. It is below the threshold required to cause an action potential and result in muscle contraction.
The minimum stimulus needed to cause a contraction is called the?
The minimum stimulus needed to cause a contraction is called the threshold stimulus. This is the minimal level of stimulation required to activate muscle fibers and initiate a contraction response.
How does neuronal firing cause muscle contraction?
When a neuron in a muscle is fired, or triggered, it sends a message to the brain telling the muscle to contract.
When a single neuron sends a strong enough impulse to a muscle that how many muscle fibers does it cause to contract?
When a single neuron sends a strong enough impulse to a muscle, it can cause multiple muscle fibers within that muscle to contract. The specific number of muscle fibers that contract will depend on factors like the size of the motor unit and the intensity of the signal from the neuron.
Long thin cells in animals that can contract and cause movement?
muscle cells
Any tissue made of cells or fibers that contract and expand to cause movement is an?
Muscle.
What Muscle cause contractions of the heart?
the lungs and the legs contract the heart for regular pulse that murmurs
Is shock from an electric outlet enough to cause pain contract your muscle?
Shock from a standard 110 volt electric outlet can cause pain and contract muscles. An electric shock can cause death. It can also cause severe burns.
