Growth hormone (GH)
Autonomic nerves innervate what three things?
Smooth muscle Cardiac muscle Gland
What effect does aging have on skeletal muscles?
loss of bone mass from demineralization and brittleness from a decreased rate of protein synthesis
Distinguish between the three types of muscle tissue?
Skeletal (striated), smooth, and cardiac.UPDATED: Dec. 1, 2009The three types of muscles and four characteristics of each:1. SMOOTHa. What/where - GI track, vessels and ductsb. Appearance - smooth - not striated - no dark and light fibersc. Nucleus - single nucleus per fiberd. Function/movement - peristalsis2. CARDIACa. What/where - heartb. Appearance - striated/striped - light and dark fibersc. Nucleus - Multi-nuceli on connecting fibersd. Function/movement - t (twitch)3. SKELETAL / STRIATEDa. What/where - skeleton of voluntary musclesb. Appearance - striated/striped - dark and light fibersc. Nucleus - mulit-nuclei per fiberd. Function/movement - t & t (twitch & tetanus)Your heart
What are the types of muscular system?
Cardiac muscles:maintain a consistent heart rate Smooth muscle:aids in food digestion and transport. Skeletal muscle:relax and contract to move a joint
What is the differences between myocardial muscles and skeletal muscles?
Skeletal muscles: packed together, attach to, and cover the skeleton. obvious striations. VOLUNTARY muscles. contract rapidly but TIRE EASILY. responsible for overal body motility. extrememly adaptable (can exert forces from only onces to 70 lbs) Cardiac (myocardial): only in the heart. striated and NOT VOLUNTARY. contracts at a steady rate. contolled by nervous system and bodily changes. ONCE YOU LOSE IT, ITS GONE FOR GOOD. CAN'T FATIGUE. has to have stimulus great enough to stimulate all of the muscles of none will contract (where as skeletal muscles can be forced into twiches where only a small part of the muscle will contract)
What measures of how fast reaction occurs?
The measure is the rate of reaction.
What is the speed at which a reaction occurs called?
The chemical term is reaction rate.
Which protect internal organs?
The important functions of the muscular system in the human body are described as follows:1. MovementsSkeletal muscles help in the voluntary movements of each and every human body part. Active contraction of these muscles occurs at the expense of energy, which creates a force that moves the body parts.2. Posture and stabilityHuman skeleton is composed of bones and the joints that are formed between them. Skeletal muscles play a major role in stabilizing human skeleton. They also help in maintaining proper posture of human body.3. Heat productionAs already stated, active contraction of muscles requires energy. Hence, muscles use a great amount of body's total energy. Due to this the body's metabolic rate is increased, producing a large amount of heat in the body.4. CirculationCardiac muscles are responsible for forcing the blood out of the heart and pumping it throughout the human body.
What are the different types of muscle fibers?
There are different types of muscle fibers. There is skeletal muscle, cardiac muscle and smooth muscle. * Skeletal muscle is attached to bones or occasionally skin. * Cardiac muscle is found in the walls of the heart. * Smooth muscle is mostly found in the walls of hollow organs such as the intestines I am currently studying anatomy and physiology at University for my nursing degree.There are three muscle Types: Skeletal, Smooth and Cardiac.All muscle cells are elongated and are called muscle fibers. Muscle contraction depends on two kinds of myofilaments (actin and myosin). The cell membrane of a muscle cell is called "sarcolemma", while the cytoplasm of a muscle cell is called "sarcoplasm".Skeletal muscle characteristics: long, thin and multi-nucleated fiber with striations, voluntary control; arranged into packages called muscles that attach to and cover the bony skeleton; contracts rapidly & vigorously, but tired easily; may exert great force.Cardiac muscle characteristics: network of branched fibers connected by gap junctions (intercalated disks); only in heart; also have striations; involuntary control; contracts at rhythmic, steady rate set by "pacemaker".Smooth muscle characteristics: lacks striations; walls of hollow visceral organs and blood vessels; involuntary control, contractions are slow & sustained.
