Kinesiology Study of motion
Bursae Fluid-filled sacs between tendons and bones
Bursitis Inflammation of a bursa
Connective tissues in the joints are Restrictive and Elastic
Joints have Ligaments
Structural Classes of Joints Fibrous, Cartilaginous, and Synovial
Based upon movement, synarthrosis means Immovable
Based upon movement, amphiarthrosis means Slightly Moveable
Based upon movement, diarthrosis means Freely Moveable
The 3 types of Fibrous joints Suture, Syndesmosis, Gomphosis
All fibrous joints are Synarthrotic
An example of a suture fibrous joint The skull
An example of a syndesmosis fibrous joint Tibia and Fibula
An example of a gomphosis fibrous joint Tooth in its socket
2 types of Cartilaginous Joints Amphiarthrosis and Synchondrosis
An example of an amphiarthorsis joint (slight movement) Intervertebral discs
An example of a synchondrosis joint (no movement) Epiphyseal growth plate
All synovial joints are Diarthrotic
Ligaments hold Bones in place
Synovial Joints have Articular Cartilage, Joint Cavity, Synovial Fluid, Synovial Membrane, Fibrous Capsule, Ligaments
Meniscus Fibrocartilage pad inside a joint cavity

Osteoarthritis Wear and tear of cartilage over time
Rhematoid Arthritis Autoimmune; Pannus
Gouty Arthritis Uric Acid build up
Lyme Disease Spread by deer ticks, bullseye
Ankylosing Spondylitis Fusion of vertebrae
Types of Movement Flexion, extension, lateral flexion, abduction, adduction, rotation, pronation, supination, eversion, inversion, circumduction, dorsiflexion, plantarflexion
Flexion is the Decrease in angle between 2 bones
Extension is the Increase in angle between 2 bones
Lateral Flexion Side bending
Abduction Moves away from center of body
Adduction Moves towards center of body
Rotation Turns on an axis
Pronation Palm down, turn downward
Supination Palm up, turn upward
Eversion Turn sole of foot outward
Inversion Turn sole of foot inward
Curcumduction Forms a circle
Dorsiflexion Points foot and toes upward
