NOTE

MUSCLES

Muscles are the tissues in the body responsible for movement, stability, and generating heat. They're composed of muscle fibers that contract to produce force.

There are over 600 muscles in the human body.

Anatomy of the muscles

The anatomy of muscles involves several key components:

  1. Muscle Fibers: Muscles are made up of individual muscle fibers, which are long, cylindrical cells that contract to produce movement.
  2. Fascicles: Muscle fibers are organized into bundles called fascicles. These fascicles are surrounded by connective tissue called perimysium.
  3. Muscle Belly: The main bulk of the muscle is called the muscle belly or muscle body. It contains numerous fascicles.
  4. Tendons: Tendons are tough bands of connective tissue that attach muscles to bones. They transmit the force generated by muscle contractions to produce movement.
  5. Origin and Insertion: Muscles have two points of attachment: the origin, which is the fixed attachment point, and the insertion, which is the movable attachment point. When a muscle contracts, it pulls on the insertion point towards the origin.
  6. Muscle Contraction: Contraction occurs when muscle fibers generate tension and shorten, pulling on the tendons to produce movement at the joints.

Types of muscles

There are three main types of muscles in the human body:

  1. Skeletal muscles: These are attached to bones by tendons and are responsible for voluntary movements like walking, running, and lifting weights.
  2. Smooth muscles: Found in the walls of internal organs, blood vessels, and airways, smooth muscles control involuntary movements like digestion, blood flow regulation, and breathing.
  3. Cardiac muscle: This type of muscle is found only in the heart and is responsible for pumping blood throughout the body. It has properties of both skeletal and smooth muscles but functions involuntarily.

EVALUATION: 1. Define muscles.

  1. Describe the anatomy of the muscles
