Muscle Anatomy and Function: A Comprehensive Guide
Muscle Anatomy and Function
Types of Muscles and Muscle Actions
Prime movers are the large muscles in the body that are responsible for large, gross movements, such as the gluteus maximus. Antagonists are also prime movers, but they oppose the action of other prime movers. For example, the bicep brachii and tricep are antagonists to one another. Synergists are small muscles that work with prime movers to add a little bit more force or reduce unnecessary movement. Fixators are synergists that stabilize

Physical and Psychosocial Needs
Need: A requirement that every person must meet to maintain their life, health, and well-being.
Biological Needs
Needs that affect the structure of the person, allowing them to live and develop through different life stages (childhood, adolescence, adulthood, and old age).
Psychic Needs
Needs related to psychic and emotional functions.
Social Needs
Needs that affect the relationships an individual has with others, i.e., social network.

Methodological Principles for Organizing Activities
Appropriate Difficulty
Activities should be placed in the “zone of proximal development”—not too far from a child’s current developmental level. This ensures significant learning.
Interest
New proposals must connect to children’s interests. At this stage, manipulation is key.
- Educators should observe, identify interests, and channel them through activities.
- Incorporate several alternative activities, allowing children to choose those that best meet
Injuries: Types, Detection, and First Aid
The Contusion
The contusion is the result of a physical injury to an agent, once the objects surface Roma (no brackets or plays) like a fist, the edge of a cabinet, wall ..
The bruises are lesions that do not break the skin but affects the tissues that are below.
As the intensity is classified as:
First grade: a blue and causes pain.
Second grade: It is more violent and larger vessels break and form a lump or nanyo and cause intense pain.
Third grade: Makes a very intense pain and a hematoma with extensive
Health and Safety at Work: Concepts, Hazards, and Medical Approaches
Health and Safety at Work
Concept
Health and safety at work refers to measures taken to protect workers from risks of injury or illness during work performance.
Routes of Entry for Contaminants
- Inhalation: Affects the respiratory system.
- Dermal: Includes the entire skin surface.
- Digestive: Includes the digestive tract.
- Mucosa Absorption: Penetration through the eye’s conjunctiva.
- Parental Via: Penetration through a break in the skin.

Endurance: Definition, Factors, Training, and Importance
What is Endurance?
Endurance is the ability to sustain a prolonged effort without showing signs of fatigue or to delay the onset of fatigue for as long as possible. It involves the capacity to perform better or recover from an activity more quickly.
Types of Endurance
- Aerobic
- Anaerobic
- Alactic: Near-maximum intensity for a short duration, producing waste products
- Lactic: Maximum intensity for a short duration, producing waste products
Factors Determining Endurance
1. VO2 Maximum
VO2 max is the maximum volume
