Q

Abduction/Adduction/Circumduction

A

Abduction moves the limb laterally away from the midline of the body. Adduction Brings the limb toward the body or across the midline. Circumduction is movement of a body region in a circular manner, in which one end of the body region being moved stays relatively stationary while the other end describes a circle.

Q

Supination/Pronation

A

Supination is the opposite motion, in which rotation of the radius returns the bones to their parallel positions and moves the palm to the anterior facing (supinated) position. Pronation is the motion that moves the forearm from the supinated (anatomical) position to the pronated (palm backward) position.

Q

Protraction/ Retraction

A

Protraction of the scapula occurs when the shoulder is moved forward, as when pushing against something or throwing a ball. Retraction is the opposite motion, with the scapula being pulled posteriorly and medially, toward the vertebral column.

Q

Depression/ Elevation

A

The upward movement of the scapula and shoulder is elevation, while a downward movement is depression. These movements are used to shrug your shoulders.

Q

Opposition/ Reposition

A

Opposition is the thumb movement that brings the tip of the thumb in contact with the tip of a finger. Returning the thumb to its anatomical position next to the index finger is called reposition.

29
Q

Pivot Joint (vertebrae in neck area)

A

At a pivot joint, a rounded portion of a bone is enclosed within a ring formed partially by the articulation with another bone and partially by a ligament.

30
Q

Hinge Joint (elbow)

A

In a hinge joint, the convex end of one bone articulates with the concave end of the adjoining bone.

31
Q

Saddle Joint (thumb)

A

At a saddle joint, both of the articulating surfaces for the bones have a saddle shape, which is concave in one direction and convex in the other.

32
Q

Ball and Socket Joint (hip)

A

The joint with the greatest range of motion is the ball-and-socket joint. At these joints, the rounded head of one bone (the ball) fits into the concave articulation (the socket) of the adjacent bone.

33
Q

Condyloid Joint (wrist)

A

At a condyloid joint (ellipsoid joint), the shallow depression at the end of one bone articulates with a rounded structure from an adjacent bone or bones.

34
Q

Plane Joint (between tarsals)

A

At a plane joint (gliding joint), the articulating surfaces of the bones are flat or slightly curved and of approximately the same size, which allows the bones to slide against each other.

35
Q

How many bones are in the cranium?

A

22 individual bones

36
Q

What is the only moveable bone in your skull?

A

Mandible (lower jaw)

37
Q

5 Vertebral Regions

A

seven cervical vertebrae, 12 thoracic vertebrae, five lumbar vertebrae, five sacral vertebrae, four small coccygeal vertebrae.

38
Q

How many vertebrae are in the cervical?

A

7

39
Q

How many vertebrae are in the thoracic?

A

12

40
Q

How many vertebrae are in the lumbar?

A

5

41
Q

Scoliosis

A

An abnormal, lateral curvature, accompanied by twisting of the vertebral column.

42
Q

Kyphosis

A

An excessive posterior curvature of the thoracic region.

43
Q

Lordosis

A

An excessive anterior curvature of the lumbar region and is most commonly associated with obesity or late pregnancy.

44
Q

What does the thoracic cage protect?

A

The heart and lungs

45
Q

Costal cartilage

A

These cartilages are made of hyaline cartilage and can extend for several inches.

46
Q

Three types of ribs

A

True ribs (7), False ribs (4), Floating ribs (2)

47
Q

Scapula

A

lies on the posterior aspect of the shoulder

48
Q

Clavicle

A

articulates with the humerus (arm bone) to form the shoulder joint

49
Q

Pectoral Gridle

A

Is anchored to the axial skeleton by a single, highly mobile joint.

50
Q

Humerus

A

The humerus is a long bone in the arm or forelimb that runs from the shoulder to the elbow.

51
Q

Radius

A

It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna.

52
Q

Ulna

A

A long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm

53
Q

Carpals

A

Are the eight small bones that make up the wrist that connects the hand to the forearm

54
Q

Metacarpals

A

Form the intermediate part of the skeletal hand located between the phalanges of the fingers and the carpal bones of the wrist which forms the connection to the forearm

55
Q

Phalanges

A

Are digital bones in the hands and feet

56
Q

Femur

A

Is the proximal bone of the hindlimb in tetrapod vertebrates

57
Q

Tibia

A

Is the larger, stronger, and anterior of the two bones in the leg below the knee in vertebrates, and it connects the knee with the ankle bones

58
Q

Fibula

A

Is a leg bone on the lateral side of the tibia, to which it is connected above and below

59
Q

Tarsals

A

Is a leg bone on the lateral side of the tibia, to which it is connected above and below

60
Q

Metatarsals

A

A group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes

61
Q

Closed fracture

A

A broken bone that does not penetrate the skin

62
Q

Open fracture

A

A fracture in which there is an open wound or break in the skin near the site of the broken bone

63
Q

Transverse fracture

A

Occurs when a bone has broken perpendicular to its the length

64
Q

Spiral fracture

A

Is a bone fracture occurring when torque is applied along the axis of a bone

65
Q

Comminuted fracture

A

A breakage of the bone into more than two fragments

66
Q

Impacted fracture

A

Occurs when the broken ends of the bone are jammed together by the force of the injury

67
Q

Greenstick fracture

A

A crack or break on one side of a long bone in the arm or leg that does not extend all the way through the bone

68
Q

Oblique fracture

A

A partial or complete break in a bone
