What else can I help you with?
Does a nerve provided impulses for many muscle fibers or just few?
A nerve can stimulate impulses to several muscle fibers. When muscle fibers are grouped they form a single muscle group like the biceps.
What muscle and nerve will you need to isolate to study the physiology of nerve fibers?
To study the physiology of nerve fibers, you would need to isolate a specific muscle and the nerve innervating that muscle. This allows for the investigation of the interaction between the nerve and muscle, observing the transmission of signals and studying the response of the muscle to nerve stimulation. Commonly studied muscles and nerves in this context include the gastrocnemius muscle and the sciatic nerve in animal models.
What nerve controls the sphincter pupillae?
The sphincter pupillae muscle is controlled by the parasympathetic fibers of the oculomotor nerve (cranial nerve III). Activation of these fibers causes constriction of the pupil (miosis).
The point of contact between the nerve and the muscle fibers it stimulates is called a?
The point of contact between the nerve and the muscle fibers it stimulates is called a neuromuscular junction. This junction allows for communication between the nervous system and the muscular system, facilitating muscle contraction in response to nerve impulses.
What maintains the tension in a muscle spindle?
The tension in a muscle spindle is maintained by intrafusal muscle fibers, which are specialized muscle fibers within the spindle that are innervated by sensory nerve fibers. These sensory fibers detect changes in muscle length and transmit signals to the central nervous system to regulate muscle tone and coordination.
What connect muscle fibers and nerve fibers?
they work together because the molecules in the blood form a whole and that whole leads them to work together

What does the neuromuscular junction connect to?
The nervous system and the muscular system are connected by the neuromuscular junction. The connection is done with synapses between nerve and muscle fibers.
Muscle fibers contract and relax in response to what?
nerve impulses
What nerve controls the sphincter pupillae?
The sphincter pupillae muscle is controlled by the parasympathetic fibers of the oculomotor nerve (cranial nerve III). Activation of these fibers causes constriction of the pupil (miosis).
What the function of the motor nerve fibers?
The motor nerve fibers help stimulate the Erector pili muscle. 1E19C8CC-7D89-BDE4-BA84-6679CBF217D2 1.02.28
What is the psoas nerve?
The psoas nerve is the nerve that innervates the psoas major muscle. It is formed by fibers of spinal nerves L2-L4.
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.
The point of contact between the nerve and the muscle fibers it stimulates is called a?
The point of contact between the nerve and the muscle fibers it stimulates is called a neuromuscular junction. This junction allows for communication between the nervous system and the muscular system, facilitating muscle contraction in response to nerve impulses.
Which two nerve fibers carry impulses from receptors in muscle to the Central Nervous System?
The two types of nerve fibers that carry impulses from muscle receptors to the Central Nervous System are Ia and II afferent fibers. Ia fibers transmit information from muscle spindle receptors, which detect changes in muscle length and rate of stretch, while II fibers relay information from Golgi tendon organs and muscle spindles, providing feedback on muscle tension and static length. Together, they play a crucial role in proprioception and the coordination of movement.
What causes muscle contraction in the leg?
Muscle contraction in the leg is caused by the interaction between nerve signals from the brain and the muscle fibers. When the brain sends a signal to the muscle, it triggers the release of calcium ions, which then bind to proteins in the muscle fibers, leading to the contraction of the muscle.
