The muscular system is made up of Multiple choice question. all the muscles plus the nerves attached to them. all the muscles, l
umka2103 [35]

Answer:

all the muscles.

Explanation:

The muscular system is composed of all muscles in the body. The main function of the muscles is to produce movement in different parts, voluntary or involuntary, creating equilibrium. Muscles are made of myocytes. There are three types of muscles: smooth muscle,  skeletal muscle, and myocardium.

  • The smooth muscle is formed by fusiform cells, mononucleated, and no transversal striations. There is a protein contraction system, but not as organized as the one of the skeletal muscle.  

Smooth-muscle can be found in organs, vessels, veins, and arteries. It provides sustained contractions, slow and rhythmical, but not voluntary.  

  • Skeletal muscle is the most abundant muscle in vertebrates, constituting the somatic musculature. It proportionates motion to extremities and digits and is responsible for the position and posture of the individual. It is also involved in eye movements, respiration, mastication, deglutition, and phonation. It moves the tongue, the superior esophagus, and the pharynx.  

The skeletal muscle is innervated by axons of the motor neurons coming from the CNS. The contraction of the skeletal muscle is voluntary and fast.  

Cells composing the striated muscle are significantly long and multinucleated. They arrange in bundles, where cells are parallel to each other.  

  • Myocardium tissue is more similar to the striated tissue than to the smooth one. However, there are some differences between them. Cardiac cells are cylindrical and smaller, with ramifications. Cardiac cells only have one nucleus, and occasionally there can be two. Actin and myosin filaments are arranged just as the skeletal ones, and the contraction of cardiac cells is molecularly very similar to the skeletal

What conclusions can you infer about the heart of an adult with poor fitness
vladimir1956 [14]
Poor fitness can cause your heart to start disfunctioning, and not beating the way it should be. If an adult is not exercising often, they can end up having major heart problems that can affect the way they see their future.

Proteins are made out of ____________. What determines the primary structure of a protein? State two functions of proteins. What
Kobotan [32]

Answer: See explanation

Explanation:

It should be noted that protein consist of amino acids. There are hundred of amino acids that are contained in protein. Examples of protein include fish, meat, eggs, nuts etc.

The amino acid sequence that can be found in the protein determines the primary structure of protein. The functions of protein include building and repair of body tissues, it also helps in maintain a proper potential of hydrogen (PH) for the body. Lastly, protein is also essential for growth as they help in cell and tissue growth.

Enzymes are catalysts that are responsible for speeding the chemical reaction rate in the body cells. Enzymes help in digestion.

Hemoglobin, is a protein that contains iron that can be found in the blood of animals. The function of the haemoglobin is to help in transferring oxygen to the tissues from the lungs.

1. Define diffusion.
anygoal [31]

Answer:

1) Diffusion is net movement of anything (e.g., atom, ions, molecules) from a region of higher concentration to a region of lower concentration.

2) Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides

3) One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but in osmosis, only the solvent molecules (water molecules) cross the membrane.

4)  Molecules tend to move from areas of higher concentration to areas of lower concentration.

I'm sorry, but I don't know how to do part #2. I think it's a lab.
