When muscles shrink from disease is it called eutrophication?
No because troph means nourishment. When muscles shrink from disuse, it is called atrophy.
Is the skin superficial to muscles below it?
No, the hypodermis is deep to the dermis. The dermis is superficial to the hypodermis.
What is the size of Chris Jericho's biceps?
chris jericho's bicep size happens to be anywhere around 17.5 to 19'' inches.. as for now.. he'z not way too tall but has a heavy built. he'z a bit fat these days but if you see him in his initial stage of wwf somewhere around 2000-01, till 2005.. he had one of the most tremendous huge bulking biceps. somewhere around 21" - 22" inches was quite a lot similar to that of 'the Rock' although jericho is smaller in height.. but both rock and jericho's bicep seemed almost same... he'z more athletic than rock, the undertaker, triple h, Batista, Goldberg and many more as such top superstar's by then.. hez still very strong at this age (41 yo). and can put many wwe superstars 'down town to china town'... i remember his backstage feud with much heavily built bill Goldberg. where the backstage reports say, he almost made him(goldberg) cry his throat out of pain.. hez athletic, strong and much more powerful as he can deceive many big wrestlers.. he trained himself all throughout his entire starting stages of his career from.. Canada to the states to the japan learning martial arts and Calgary mixed wrestling.. hez a trained wrestler and can easily beat down almost many opponents in real fight...
What is a injury to either a muscle or the tissue that connects muscles to bone called a tendon?
strain
Axons and dendrites are sometimes called nerve fibers. Nerve fibers are often arranged in parallel bundles covered with a connective tissue, something like a package of uncooked spaghetti wrapped in cellophane. A bundle of nerve fibers is called a nerve.
Kinds of Neurons:Three kinds of neurons are found in the body-- sensory neurons, interneurons, and motor neurons.A sensory neuron picks up stimuli from the internal or external environment and converts each stimulus into a nerve impulse. The impulse travels along the sensory neuron until it reaches the interneuron, usually in the brain or spinal cord. An interneuron is a neuron that carries nerve impulses from one neuron to another. Some interneurons pass impulses from sensory neurons to motor neurons. A motor neuron sends an impulse to a muscle or gland, and the muscle or gland reacts in response.
How a Nerve Impulse TravelsThe Synapse:What happens when a nerve impulse reaches the axon tip at the end of a neuron? At that point, the impulse can pass to the next structure. Sometimes the structure is a dendrite of another neuron. Other times, the structure is a muscle or a cell in another organ, such as a sweat gland. The junction where one neuron can transfer an impulse to another structure is called a synapse. (SIN aps). How an Impulse is Transferred:For a nerve impulse to be carried along at a synapse, it must cross the gap between the axon and the next structure. The axon tips release chemicals that carry the impulse across the gap.You can think of the gap at a synapse as a river, and an axon as a road that leads up to the riverbank. The nerve impulse is like a car traveling on the road. To get to the other side, the car has to cross the river. The car gets on a ferry boat, which carries it across the river. The chemicals that the axon tips release are like the ferry, carrying the nerve impulse across the gap.
What muscle is used in blowing?
The ab muscles are used for forcibly blowing air. A common misconception is that the diaphragm allows forced expiration when it is, in fact, used for inspiration. The diaphragm muscle will flatten (from its relaxed dome shape) when contracting allowing negative pressure to draw air into the lungs.
Muscles are heated in 2 ways. When ATP is broken down for muscular contractions, the majority of energy released is actually thermal energy thus heating the intramuscular environment. The friction of muscle proteins as they contract also produces a certain amount of heat.
Which type of muscle is slanted outward away from the midline?
A muscle that is slanted outward from the midline is oblique.
What is the step in muscle contraction after actin changes shape?
Actin Changes Shape
Apex
Myosin binds to Actin
APEX
What does the heart muscle need in order to function?
Your heart needs blood, oxygen, and energy to function!!!!!!!!
What is the Muscle that is predominantly responsible for a movement?
The muscle type responsible for body movements is skeletal muscle. This type of muscle is under voluntary control (unlike cardiac and smooth muscle) meaning that we can consciously control the movements we make.
The specific skeletal muscle responsible for movement will depend on what movement is being made.
What happens when The radial muscles of the iris contract?
When the eye is stimulated by bright light, the circular muscle of the iris contracts, decreasing the size of the pupil.
What muscle is contracted to flex your forearm?
There are about 20 muscles in a forearm, consisting of flexors and extensors. Flexors are responsible for flexing the forearm, wrist, and fingers.
What part of a muscle fiber junctions with a motor neuron?
There is no junction. Motor neurons are riddled throughout the muscle spindles. Every muscle spindle has a nerve supply or it would not function. think about the way capilaries infiltrate mucles, it's pretty finite. when you are talking about the neurons you are talking about a finite thing, there are billions of them in your body.
They attach to the facial bones, just as all the other muscles in the body attach to bone. They are there to act on the bones and cause movement. An exception to that would be the cardiac muscle, among a few others, but they don't occur on the face.
How does the deltoid of the cat differ from the deltoid of a human?
The Deltoid in a human is on large muscle and the cat has an upper Clavo Brachialis and a lower Pectoantebrachialis, two muscles instead of one larger one. The Trapezius muscle is one large muscle in humans and in cats is 3 smaller muscles called the Clavobrachialis, Acromiodeltoid, and Spinodeltoid muscles.
What is the name of muscles attached to the bones of the skeleton?
.. the muscles attached the bones in your body help move the body around if you didnt have any muscles in your bodyall you would be was bones basicly. .. but ... i dont know what the muscles are called that are attached the the bones in the body of a human and or animal
