Does the nervous system transmit information that tells your muscle and otherinternal organs how to react?
The nervous system does not tell muscles how to react. The nerves transmit electrical pulses that make muscles contract. Different nerves attached to different muscles strands control how a muscle reacts. For example, nerves going to some arm muscles when they contract may make your elbow bend. Nerves going to a different set of muscles when made to contract may make your arm straighten out at the elbow. Using all muscles in that area allows you to maintain a bent elbow in a specific position.

What system consist of sensory and motor neurons associated with voluntary actions?
The somatic nervous system consists of sensory and motor neurons that are associated with voluntary actions. Sensory neurons transmit sensory information from the body to the central nervous system, while motor neurons transmit signals from the central nervous system to muscles to initiate movement. This system allows for conscious control over skeletal muscle movement.
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 is somatic nervous system?
The somatic nervous system transmits sensory messages to the central nervous system. The somatic nervous system is a sub group of the peripheral nervous system, it mainly controls voluntary muscles and sense organs.
What does second order mean in human anatomy?
Second order commonly refers to muscles anatomical Origin, Insertion, Innervation, Function.Origin: point where the muscle starts fromInsertion: point of muscle insertion or attachmentInnervation: which nerve(s) innervate or supply nervous impulses to the muscleFunction: the function of the muscle- what the muscle does.
What system stimulates muscle to contract and interprets information from sensory organs?
The central nervous system.
What does it mean that neurons are excitable and how does this property contribute to their function in the nervous system?
Neurons being excitable means they can generate electrical signals in response to stimuli. This property allows them to communicate with each other and transmit information throughout the nervous system. Excitability is essential for processes like sending signals between neurons, controlling muscle movement, and processing sensory information.
The branch of the nervous system that receives sensory information and controls muscle movements is the?
somatic nervous system which is a part of peripheral nervous system.
What relays information to the muscles from the brain?
The information from the brain is relayed to the muscles primarily through motor neurons. These neurons transmit signals from the central nervous system, specifically the spinal cord, to the muscle fibers. This communication allows the brain to control muscle contractions and movements. Additionally, neurotransmitters, such as acetylcholine, play a crucial role in facilitating the transmission of these signals at the neuromuscular junction.
Do you have electrical energy in your nerves?
Yes, electrical signals are used by the nervous system to transmit information between neurons and to control muscle movement. Neurons generate electrical impulses through the flow of ions across their cell membranes.
What part of the nervous system coordinates incoming information from the senses and sends instructions to the muscles and glands?
The central nervous system, which consists of the brain and spinal cord, coordinates incoming sensory information and sends instructions to muscles and glands. This information processing allows for both voluntary and involuntary responses to stimuli.
What are the only two types of cells that have excitable membranes?
The only two types of cells that have excitable membranes are neurons and muscle cells. Neurons transmit electrical signals in the nervous system, while muscle cells generate electrical signals that lead to muscle contraction.
What muscle does the cerebo-spinal nervous system control?
The cerebrospinal nervous system, primarily comprising the brain and spinal cord, controls skeletal muscles through motor neurons. These neurons transmit signals from the central nervous system to the muscles, enabling voluntary movements. Additionally, it regulates reflexes and some involuntary muscle actions, like those in the heart and digestive system, through the autonomic nervous system, which is part of the broader peripheral nervous system.
