What else can I help you with?
All of these neurons release acetylcholine as a neurotransmitter except?
specific cardiac and smooth muscle fibers
What components of nerves are involved in skeletal muscle movement?
Motor neurons within the peripheral nervous system carry signals from the brain and spinal cord to the skeletal muscles, while muscle fibers receive and respond to these signals, leading to muscle contraction and movement. Motor units, comprising a motor neuron and the muscle fibers it innervates, work together to control muscle movement output.
What make up nervous muscle tissue?
Muscle tissue made up of elongated muscle fibers, fibers that contract in response to stimuli. Nervous Tissue is made up of neurons and neurological cells.
What is the relationship between the number of motor neurons recruited and the number of skeletal muscle fibers innervated?
Typically, hundreds of skeletal muscle fibers are innervated by a single motor neuron.Completed
Which of these parts receive nerve impulses from the central nerous system causing muscle fibers to contract?
The motor neurons carry impulses from the central nervous system to the muscles. These impulses may be generated autonomically (instinctively) or through voluntary control by the brain.
What kind of nerves control skeletal muscle contraction?
The muscle spindle helps to control the contraction of muscles. It is a special sensory organ that uses sensory neuronal fibers to find how long the intrafusal muscle fibers are.
What makes up muscle tissue?
Muscle tissue made up of elongated muscle fibers, fibers that contract in response to stimuli. Nervous Tissue is made up of neurons and neurological cells.
What do impulses passed from motor neurons release?
Impulses passed from motor neurons release neurotransmitters at the neuromuscular junction. This leads to the stimulation of muscle fibers and ultimately results in muscle contraction.
What special cell in our muscles that receive message form motor neurons?
The special cells in our muscles that receive messages from motor neurons are called muscle fibers or myocytes. When a motor neuron sends an electrical signal, it releases neurotransmitters at the neuromuscular junction, which then bind to receptors on the muscle fibers. This triggers a series of events that lead to muscle contraction. The coordinated activity of these muscle fibers allows for precise movement and force generation in the body.
What chemical element do neurons pour into the muscle fibers to make them contract?
"Caleotidomastusidialis" element maskes the muscles contract.
What Neurotransmitter that activates skeletal muscle fibers?
Acetylcholine is the neurotransmitter that activates skeletal muscle fibers at the neuromuscular junction. It plays a crucial role in transmitting signals from motor neurons to muscles, leading to muscle contraction.
If a person has Duchenne and Muscular Dystrophy how are the neurons affected?
Duchenne Muscular Dystrophy (DMD) primarily affects muscle fibers rather than neurons directly; however, the condition can lead to secondary effects on the nervous system. As muscle degeneration progresses, motor neurons may experience changes due to the loss of muscle input and altered signaling. Additionally, the overall physical inactivity and muscle weakness can impact motor neuron health over time, potentially leading to further complications in muscle control and coordination.
