Anatomy- Introduction and Connective Tissue Coverings

Muscle Types

Smooth, skeletal, and cardiac

Characteristics of skeletal muscles

Striated and under voluntary control

Skeletal Muscle Functions

Maintain posture, balance, and generate heat through muscle contractions

What are muscles?

Muscles are organs that utilize chemical energy from surrounding nutrients to contract

Fascia

Holds muscles in place and compartmentalizes them as units. Covers the muscle directly and separates them from surrounding tissues.

Epimysium

Blends into fascia and surrounds the muscle.

Perimysium

Separates tissue into fascicles and sprouts from within the epimysium

Fascicles

Bundles of muscle fibers, contractile units of a muscle

Endomysium

Innermost tissue, separate and surround each muscle fiber within the fascicles

2 Connective Tissue Connections

1. Run off muscle ends to attach to the surface of other bones to create a tendon.

2. Form broad, fibrous sheets called aponeuroses.

Tendinitis

Inflamed and swollen tendons after repetitive stress/ injury

Tenosynovitis

Connective tissue sheet on the tendon becomes inflamed (tenosynovium)
