The Skeletal Muscular System Bone is living tissue

The Skeletal & Muscular System

Bone is living tissue, providing support and protection an working with the muscular system. Muscular Skeletal Provides movement Composed of: internally and externally • Bone • Cartilage Provides shape to the body and protects the organs

The bones and joints together compose a complex system of levers and pulleys. Flexion- the shortening of a muscle to bend a joint. Extension- lengthening of a muscle to straighten a joint.

Bones • Long Bones- found in the limbs. • Short Bones- occur in the knee and hock.

Bones • Flat Bones- enclose cavities with vital organs. • Irregular Bones- include the vertebrae and some bones of the skull. • Joint or Articulation- the union of two or more bones or cartilages.

Synovial fluid is a clear, slightly yellowish fluid that acts as a lubricant to aid in movable joints.

Bones • Flat Bones- enclose cavities with vital organs. • Irregular Bones- include the vertebrae and some bones of the skull.

Axial Skeleton Also called the trunk Appendicular Skeleton Includes the limbs

The horse spinal column is a flexible column of small bones called vertebrae.

Muscles • Smooth Muscle- involuntary (automatic) • Digestive tract • Respiratory, Urinary and Reproductive Systems

Muscles • Cardiac Muscle- involuntary (automatic) • Only found in the heart • Circulatory functions

Muscles • Skeletal Muscle • voluntary muscles are usually attached to the bony levers of the skeleton. • Arranged in opposing pairs
