Study Notes
Introduction to Human Anatomy
- Deep fascia is tough connective tissue that covers, protects, and unifies structures in the body.
Muscles
- Skeletal Muscles: Responsible for movement and energy storage.
- Smooth Muscles: Found in hollow tubes like the intestines and blood vessels, facilitating involuntary movements.
- Cardiac Muscle: Known as myocardium, present only in the heart.
Bone Classification
- Bones are classified based on:
- Location: Axial (skull, vertebrae, ribs) and Appendicular (limbs and girdles).
- Shape: Long, short, flat, irregular, and sesamoid bones.
Joints Between Bones
- Fibrous Joints: No movement; bones are joined by fibrous tissue (e.g., skull sutures).
-
Cartilaginous Joints: Separated by fibrocartilage; consist of:
- Primary (no movement)
- Secondary (limited movement, e.g., intervertebral joints).
- Synovial Joints: Feature a cavity allowing free range of movement (e.g., shoulder and knee joints).
Structure of Synovial Joints
- Composed of:
- Synovial Cavity: Space between bones.
- Synovial Fluid: Lubricates joints, reducing friction.
- Synovial Membrane: Lines the cavity, producing synovial fluid.
- Fibrous Capsule and Ligaments: Provide stability and support.
Types of Synovial Joints
- There are six types, including:
- Condyloid (Ellipsoidal) Joints: An oval bony projection fits into an oval depression of another bone; allows movement in multiple axes (e.g., shoulder, hip joints).
Arthritis
- Inflammation of joints leading to swelling and pain.
-
Types of Arthritis:
- Gouty Arthritis: Caused by deposition of sodium urate crystals due to high uric acid levels in blood, leading to acute pain and swelling, commonly in feet and hands; also known as "Disease of Kings".
