Study Notes

Skeletal System Overview

  • The skeleton is referred to as the infrastructure of the body, providing a structural framework.
  • The combined system of bones and muscles is called the musculoskeletal system.
  • Self-generated movement in the body is termed locomotion.

Bone Tissue and Functions

  • Bone tissue can also be referred to as osseous tissue.
  • The process of blood cell formation is known as hematopoiesis.
  • Vertebrae are categorized as irregularly shaped bones.

Skull and Rib Cage Structure

  • The skull consists of 8 cranial bones and 14 facial bones.
  • The thoracic cavity is encased by the ribs, vertebral column, and sternum.

Anatomical Relationships

  • The clavicle is commonly known as the collar bone, while the shoulder blade is referred to as the scapula.
  • In anatomical positioning, the ulna runs parallel with the little finger and the radius aligns with the thumb.
  • The shin bone is identified as the tibia.
  • The big toe is known as the hallux.

Joints and Movement Types

  • Articulations define the areas where two bones meet to form a joint.
  • Synovial joints are not categorized as fibrous joints.
  • Synchondrosis and symphysis are both types of cartilaginous joints.
  • Synarthrotic joints are categorized as immovable joints.
  • Diarthrotic joints, also known as synovial joints, are characterized as freely moving.
  • Amphiarthrotic joints allow for slight movement.

Osteoporosis and Women's Health

  • Menopausal women experience a higher risk of osteoporosis due to decreased estrogen levels.

Types of Synovial Joints

  • The six types of synovial joints are:
    • Gliding
    • Hinge
    • Pivot
    • Condyloid
    • Saddle
    • Ball and socket
