1
The sarcoplasmic reticulum constitutes the main intracellular calcium store in striated muscle and plays an important role in the regulation of excitation–contraction–coupling (ECC) and of intracellular calcium concentrations during contraction and relaxation.
2
Links the way in which the ATP is provided, ie the form of participation of the different energy systems and the type of physical activity that is performed
3
When they are at rest, neurons and axons are electrically charged thanks to the ions (sodium, potassium, chlorine) that are on the outside and inside the cells. When the neuron is excited it is depolarized creating an action potential
4
Muscles develop tension and become shortened or stretched
5
Is formed by the heart and the blood vessels that are united forming a closed circuit through which the blood circulates.
6
Relative to the connection between nerves and the muscles that stimulate.
7
In them takes place the breathing, process that implies the obtaining of energy from organic molecules and its conversion in molecules of ATP
8
Union of the muscle at the less mobile bone point. The origin represents that muscular union that works like a stationary support point, Is characterized by stability or low mobility.
9
Metabolism is a set of physical and chemical processes that occur in cells, Convert nutrients from food into energy needed for the body to fulfill all its vital functions, such as breathing, digestion, circulating blood, maintaining body temperature and eliminating
10
The ligaments are bands of elastic tissue that, in most cases, join the bones in the joints, Key in joint movement by controlling the range of motion and stabilizing them by causing the bones to move with proper alignment
11
Practical work that is done for the acquisition, development or conservation of a faculty, of an aptitude or of a skill
12
Is where the synthesis of proteins occurs in living beings, formed by several molecules of ribosomal RNA associated with more than 50 different proteins
13
Muscular effort or physical exercise that develops with or without oxygen consumption
14
Strength, ability, and physical ability to move objects or people who have weight throughout space
15
Are substances released by endocrine cells into the blood and exert their action on other cells known as target cells, They participate in the coordination of processes of growth, differentiation, reproduction, metabolism, apoptosis and others.
16
Is found in the center of eukaryotic cells, Which contain all the necessary genetic data at the time of reproduction, The cell nucleus is composed of a soft organelle that is made up of DNA and RNA.
17
Are bands of nervous tissue and whitish color that binds the muscles to the bones. Have a great tensioning force, although their elasticity is very reduced and they are resistant to the stretch.
18
The muscles are tissues or organs of the human body, the locomotor apparatus characterized by its ability to contract and usually by a response to a nervous stimulus
19
A cord composed of many filaments or nerve fibers that, starting from the brain, the spinal cord or other centers, are distributed throughout the body, conducting nerve impulses.
20
The cell is an anatomical and functional unit of living beings composed of a cytoplasm and a membrane-protected nucleus
