What else can I help you with?
What fibers carry information from the skin joints and skeletal muscles to the central nervous system?
parasympathetic
Sensory information concerning position and balance motor neurons that control skeletal muscles travel over what type of fibers?
Sensory information concerning position and balance motor neurons that control skeletal muscles travel over proprioceptive fibers. These fibers are responsible for conveying information about the body's position, movement, and orientation to the central nervous system.
What do somatic nerve fibers innervate?
Somatic nerve fibers innervate the structures responsible for conscious touch, pain, and temperature sensation in the skin, muscles, and joints. They are part of the peripheral nervous system and transmit sensory information from the body to the central nervous system.
Skeletal and smooth muscles move when nerve impulses sent from the blank stimulate the muscle fibers telling them to either contract or relax?
Skeletal and smooth muscles move when nerve impulses sent from the nervous system stimulate the muscle fibers, instructing them to either contract or relax. In skeletal muscles, this stimulation comes from motor neurons, while smooth muscle contraction is typically regulated by autonomic nerve fibers. These signals trigger a series of biochemical events that lead to muscle contraction and relaxation.
Skeletal and smooth muscles move when nerve impulses sent from the stimulate the muscle fibers telling them to either contract or relax?
Skeletal and smooth muscles contract or relax in response to nerve impulses that stimulate their muscle fibers. In skeletal muscles, motor neurons release neurotransmitters at the neuromuscular junction, triggering contractions. Smooth muscles, which are involuntary, respond to autonomic nervous system signals and various hormones. This process allows for coordinated movements and functions throughout the body.
True or false smooth muscle fibers are located in small skeletal muscles?
smooth muscle fibers are located in small skeletal muscle
What gives skeletal muscles their strength?
Skeletal muscles get their strength from their large numbers of muscle fibers, which contain contractile proteins that generate force during muscle contraction. The organization of these fibers in parallel bundles allows for coordinated and powerful movement. Additionally, the recruitment of more motor units by the nervous system can also contribute to increased muscle strength.
What are the key differences between skeletal and cardiac muscle in terms of their structure and function?
Skeletal muscles are attached to bones and help with movement, while cardiac muscles are found in the heart and help pump blood. Structurally, skeletal muscles have long, cylindrical fibers with multiple nuclei, while cardiac muscles have branching fibers with a single nucleus. Functionally, skeletal muscles are under voluntary control, while cardiac muscles contract involuntarily.
What is role of spindle fibers?
Spindle-shaped muscle fibers are skeletal muscles that produce external mobility to the body.
What is the role of the spindle fibers?
Spindle-shaped muscle fibers are skeletal muscles that produce external mobility to the body.
What muscle fibers pull in different directions depending on stimulation?
Skeletal muscles
DoesAfferent fibers carry messages to the muscles true or false?
False. Afferent fibers carry sensory information from the peripheral nerves to the central nervous system, such as information about touch, pain, temperature, etc. Efferent fibers, on the other hand, carry signals from the central nervous system to the muscles to initiate movement.
