Skeletal System

The skeletal system serves as the body's framework, composed of bones, cartilage, and ligaments. It provides structure, facilitates movement, and protects vital organs. The adult human skeleton consists of 206 bones, categorized into two major divisions: the axial skeleton (skull, vertebral column, rib cage) and the appendicular skeleton (limbs and pelvic girdle).

  • Functions:
    • Support: Provides shape and support to the body.
    • Protection: Shields organs like the brain and heart.
    • Movement: Works with the muscular system to enable mobility.
    • Mineral Storage: Stores minerals such as calcium and phosphorus.
    • Blood Cell Production: Houses bone marrow, where blood cells are produced.
  • Bone Types:
    • Long Bones: (e.g., femur) support weight and facilitate movement.
    • Short Bones: (e.g., carpals) provide stability and support.
    • Flat Bones: (e.g., skull) protect internal organs.
    • Irregular Bones: (e.g., vertebrae) serve varied functions.

Muscular System

The muscular system is vital for body movement and maintaining posture. It consists of three types of muscle tissues: skeletal, smooth, and cardiac. Skeletal muscles are under voluntary control, while smooth and cardiac muscles function involuntarily.

  • Functions:
    • Movement: Enables locomotion and movement of substances within the body.
    • Posture Maintenance: Helps maintain body position against gravity.
    • Heat Production: Generates heat through muscle contractions.
  • Muscle Types:
    • Skeletal Muscle: Voluntary and striated, attached to bones.
    • Smooth Muscle: Involuntary and non-striated, found in organs.
    • Cardiac Muscle: Involuntary and striated, makes up the heart.

Understanding the skeletal and muscular systems is crucial for comprehending how the body moves and functions. Their intricate relationship facilitates various bodily processes, emphasizing the importance of maintaining overall health through exercise and proper nutrition.
