What else can I help you with?
Is skeletal muscle considered an organ in the human body?
Yes, skeletal muscle is considered an organ in the human body. It is made up of muscle tissue, blood vessels, nerves, and connective tissue, all working together to allow movement and support the body.
Is your upper arm a skeletal or muscle system?
It has organs belonging to the muscular system, the skeletal system, the cardiovascular system, the integumentary system and the nervous system in it. Muscles, bones, blood vessels, nerves and skin.
What function does the submucosa have?
The submucosa supports the mucosa and joins the mucosa to the bulk of overlying smooth muscle. Blood vessels, lymphatic vessels, and nerves all run through here.
List three reasons why the connective tissue wrapping of skeletal muscles are important?
1. Provide a route for entry and exit of nerves and blood vessels that serve the muscle fibers. 2. Provide strength to muscle as a whole3. Support and bind muscle fibers
Does epimysium contain nerves and blood vessels?
Yes, the connective tissues of the epimysium contain the blood vessels and nerves that supply the muscle fibers
Does sympathetic and parasympathetic nerves supply voluntary skeletal muscles?
No, sympathetic and parasympathetic nerves do not supply voluntary skeletal muscles. These nerves primarily innervate smooth muscle, cardiac muscle, and glands, helping to regulate involuntary functions in the body. Voluntary skeletal muscles are under the control of the somatic nervous system.
What is the function of End Plates?
A motor endplate is a large special synaptic contact between motor axons and each skeletal muscle fiber. Each muscle fiber forms one endplate. Its function is to transmit impulses from nerves to muscles.
At what junction do nerves contact skeletal muscle fibers?
Motor neurons meet the muscle cells at neuromuscular junctions. Neurotransmitters are passed from the nerve across a synaptic cleft to the muscle to make it contract. Any damage to this nerve will mean that those cells will not contract (move).
Why are Motor nerves that supply skeletal muscle the last to be inhibited?
Because the nerve supply for muscles are mixed
What is the function of the hilus?
It is a depression where vessels, nerves or ducts enter a bodily organ
What muscle must be supplied by a somatic motor nerve?
All skeletal muscles in the body must be supplied by somatic motor nerves. These nerves carry signals from the brain to the muscles, controlling voluntary movements.
What diseases can you find in the muscular system?
Poliomyelitis - viral infection of the nerves that control skeletal muscle movement Muscular Dystrophies - (most commonly a mutation of dystrophin) muscle function is impaired, causing weakness Myasthenia Gravis - autoimmune disease affecting the neuromuscular junction.
