Shoulder Girdle (scapulothoracic) movements
Protraction (abduction)
Forward movement of the shoulder girdle in the horizontal plane away from the spine. Abduction of the scapula

Accessory Motion: Roll(rock)

Accessory Motion: Glide (slide, translation)
A specific point on one articulatin surface comes in contact with a series of points on another surface
Accessory Motion: Spin
A single point on one articular surface rotates about a single point on another articular surface. Motion occurs around some stationary longitudinal mechanical axis in either a clockwise or counterclockwise direction.
Structural Kinesiology
The study of muscles, bones, and joints as they are involved in the science of movement.

Proximal
Nearest the trunk or the point of origin
Radial
Relating to the radial (lateral) side of the forearm or hand
Scapular plane
In line with the normal resting position of the scapula as it lies on the posterior rib cage; movements in the scapular plane are in line with the scapular; which is at an angle of 30 to 45 degrees from the frontal plane
Sinister
Relating to or situated to the left or on the left side of something
Superficial
Near the surface; used to describe relative depth or location of muscles or tissue
Superior (supra)
Above in relation to another structure, higher, (CEPHALIC)
Superolateral
Above and to the outside
Superomedial
Above and toward the midline or inside
Supine
Face-upward position of the body; lying on the back
Tibial
Relating to the tibial (medial) side of the lower extremity
Ulnar
Relating to the ulnar(medial) side of the forearm or hand
Ventral

Relating to the palm of the hand or sole of the foot
Anterversion
Abnormal or excessive rotation forward of a structure, sucj as femoral anteversion

Increases curving of the spine outward or backward in the sagittal plane
Lordosis
Increased curving of the spine inward or forward in sagittal plane

Sagittal, Anteroposterior, or AP plane
Bisects the body from front to back dividing the body into right and left halves

Skeletal Functions
1. protection of vital soft tissues such as the heart, lungs, and brain
2. Support to maintain posture
3. Movement by servingas points of attachment for muscles and acting as levers
4. Storage for minerals such as calcium and phosphorus
5. Hemopoiesis, which is the process of blood formation that occurs in the red bone marrow located in the vertebral bodies, femur, humerus, ribs and sternum.
Synarthrodial (immovable) joints
Suture: Found in the sutures of the cranial bones. The sutures of the skull are truly immovable beyond infancy.
Gomphosis: Found in the sockets of the teeth. The socket of a tooth is often referred to as a Gomphosis (type of joint in which a conical peg fits into a socket). Normally, there should be essentially no movement of the teeth in the mandible or maxilla
Amphiarthrodial (slightly movable) joints
Structurally divided into 3 types:
Syndesmosis: type of joint held together by strong ligaments structures that allow minimal movement between the bones.Ex: coracoclavicular joint and the inferior tibiofibular joint.
Symphysis: type of joint separated by fibro cartilage pad that allows very slight movement between bones. Ex: symphysis pubis and intervertebral disks
Synchondrosis: type of joint separated by hyaline cartilage that allows very slight movement between bones. Ex: costochondral joints of ribs with the sternum
Diarthrodial (freely movable) joints
Also known as synovial joints, freely movable. Sleevelike covering of ligamentpus tissue known as joint capsule surrounds the bony ends forming the joints.
Diarthrodial: Arthrodial (gliding, plane) joint
Characterized by two flat, or plane, bony surfaces that butt against each other. Permits limited gliding movement.
Ex: carpal bones of wrist and the tarsometatarsal joints of the foot.
Diarthrodial: Condyloidal (ellipsoid, ovoid, biaxial, ball-and-socket) joint
bones permit movement in two planes without rotation. Examples are the wrist (radiocarpal joint) between the radius and the proximal row of the carpal bones or the second, third, fourth, and fifth metacarpophalangeal joints.
Diarthrodial: Enarthrodial (spheroidal, multiaxial ball-and socket) joint
Most like true ball-and socket in that it permits movemet in all planes. Ex are the shoulder (glenohumeral) and hip (acetabularfemoral) joints.
Diarthrodial: Ginglymus (hinge) joint
Wide range of movement in only one plane.
Examples: elbow (humeroulnar), ankle (talocrural), and knee (tibiofemoral) joints
Diarthrodial: Sellar (saddle) joint
THis type of reciprocal reception is found only in the thumb at the carpometacarpal joint and permits ball-and-socket movement, with the exception of slight rotation
Diarthrodial: Trochoidal (pivot, screw) joint
This is a type of joint with a rotational movement around a long axis.
Example: rotation of the radius on the ulna at the proximal and distal radioulnar joints
5 major factors affect total stability and mobility of joint
Bones
Cartilage
Ligaments and connective tissue
muscles
Proprioception and motor control
Range of motion
area through which a joint may normally be freely and painlessly moved
Abduction
Lateral movement away from the midline of the trunk in the frontal plane.
Ex: Raising the arms or legs to the side horizontally
Adduction
Movement medially toward the midline of the trunk in the frontal plane.
Ex: lowering the arm to the side or thigh back to anatomical position
Flexion
Bending movement that results in a decrease of the angle in a joint by bringing bonestogether, usually in sagittal plane.
Ex: elbow joint when the hand is drawn to the shoulder
