Classification
Types of joints? (3)
Fibrous, Cartilaginous, Synovial
Synovial joints are the ____ common types of joints in the body.
Most
Allows backward and forwards and side-to-side motion, but no rotation.
Saddle
Depression
Three types of muscle tissue
Skeletal, Smooth, Cardiac
A fixed, or immovable, joint that connects bones. It is made primarily of collagen.
Fibrous Joint
Synovial joints are classified by the ____ they allow.
movements
Allows a gliding movement
Plane
Bending a joint that decreases the angle between bones
Flexion
Tough cords or sheets of connective tissue that attch muscles to bones.
Tendons
A joint that has some motion to it with hyaline or fibrous cartilage present, in the space between articulating bones.
Cartilaginous Joint
6 types of synovial joints
Saddle, Ball & Socket, COndyloid, Plane, Hinge, Pivot
Allows limited rotating movements
Pivot
Moving toward the axis, or midline, of the body.
Adduction
These muscle movements pull on bone and move the body.
Contraction or shortening
A moveable joint that contains synovial fluid in the space around it to reduce friction; the most common type of joint in the body.
Synovial Joint
Determines what types of movement are possible.
The shape of the bone surfaces involved in each joint
Allows backward, forward, sideways, and rotating movements.
Ball and Socket
Moving in a circular motion
Circumduction
The smallest muscle unit
Sarcomere
The sutures of the skull are held together by dense connective tissue. How are these joints structurally classified?
Fibrous
A key feature of a synovial joint.
Synovial Fluid
Allows back and forth movement in multiple directions without rotation.
Condyloid
Bending at the ankle to lift the toes toward the knee.
Dorsiflexion
The theory of how proteins cause muscle contraction
Sliding Filament Theory
