56
The functional classification of joints is based on the amount of ______ that can occur at the joint.
Movement
57
There are three basic types of joints based on functional activities:

Amphiarthroses
Diarthoroses
58
Synarthroses
Immovable joints
59
Amphiarthroses
Slightly moveable joints
60
Diarthoroses
Freely movable joints
61
The structural classification of joints relies on the type of ______ ______ which binds articulating surfaces together and on the presence or absence of a joint cavity.
Connective tissue
62
There are three structural categories of joints:
Fibrous joints
Cartilaginous joints
Synovial joints
63
In ______ _____ the articulating bones are firmly bound together by dense fibrous connective tissue.
Fibrous joints
64
Fibrous joints, the joint cavity is not present. They are are very strong and permit:

65
Fibrous joints have two major types of joints in the structural division are:
Sutures & Syndesmoses
66
Are articulating bones that are held very close together by dense connective tissue. Functionally classified as synarthrosis or immovable joints. Example: joint found between the cranial and facial bones of the skull.
Sutures
67
Are the articulating bones that are united by a band of dense connective tissue. The amount of movement at this type of joint depends upon the length of the connecting fiber.
Example: joint found at the distal articulation between the tibia and fibula is classified as synarthrosis, or immovable true movement is prevented: best described as give
Syndesmoses
68
In these joints the articulating bones are bound to each other by cartilage. These joints lack a joint cavity and permit little or no movement.
Cartilaginous
69
Cartilaginous have two major types of joints in the structural division are:
Synchondroses
| Symphyses
70
Articulating bones are connected by hyaline cartilage. Functionally classified in the adult as synarthrosis, or immovable joints. Examples: joint formed by the coastal cartilage is of rib number one and the manubrium of the sternum; epiphyseal plates in the long bones of children.
Synchondroses
71
Articulating bones are connected by fibrocartilage. Functionally classified as for amphiarthroses, Or slightly moveable joints. Examples: the intervertebral discs between the bodies of the vertebrae: pubic symphysis
Symphyses
72
Most joints in the body. The movement is limited only by ligaments, muscles, tendons, or adjoining bones. Are characterized as diarthrosis, or freely moveable joints.
Synovial Joints
73
The articulating bones are separated by a fluid filled joint cavity. Articular cartilage (hyaline) covers the surface of the articulating bones. The joint cavity is enclosed by an articular capsule, consisting of the outer layer, the fibrous capsule, and an inner layer, formed by the synovial membrane.
The synovial membrane secretes synovial fluid, which fills the synovial cavity, lubricates the joint, and provides nourishment for the articular cartilage.
Synovial joints are reinforced and strengthened by band like ligaments composed of dense regular connective tissue.
Distinguishing features of a synovial joint.
74
Synovial joints can be divided into six categories according to the shape of the articulating surfaces and the type of movement allowed.
(i) Plane (gliding) joints
(ii) hinge joints
(iii) pivot joints
(iv) condyloid (ellipsoid) joints
(v) saddle joints
(vi) ball and socket joints
75
articulating surfaces are essentially flat. Movement does not occur around an access non-axial: only allows slight movement. Examples: the joints between the carpal bones of the wrist and between the tarsal bones of the ankle; sternocostal joint between the sternum and the ribs number 2 to 7; vertebrocostal joint between the vertebrae in the ribs snow already said that there are no: intervertebral joint between the articular processes of the vertebrae; joint between tarsals and metatarsals; joint between carpals and metacarpals of digits numbers 2 to 5; joint between the lateral end of the clavicle and the acromion of scapula.
(i) Plane (gliding) joints
76
A convex surface of one bone fits into concave surface of another bone. Movement occurs around a single access monoaxial; permits flexion and extension. Examples: elbow joint; joint between the phalanges; ankle joint; knee joint modified hinge
(ii) hinge joints
77
Around its surface of one bone fits into a ring like portion of another bone. Movement occurs around a single Access Main axle; permits rotation. Examples: joint between the atlas and axis; joint between the head of the radius and the ulna
(iii) pivot joints
78

Movement occurs around two axes biaxial; permits all angular motions: flexion and extension, abduction and adduction, and circumduction. Oh and rotation. Example: joint between the carpal and metacarpal bone of the thumb.
(iv) condyloid (ellipsoid) joints
79
each articular surface has both convex and concave areas; the surface of one bone fits as a "rider" into the saddle of the other bone. Movement occurs around 2 axes (biaxial); permits all angular motions: flexion and extension, abduction and adduction, circumduction and rotation. Example: joint between the carpal and meta carpal bone of the thumb
(v) saddle joints
80
