16
Q

THERE IS (NO/HAVE) CAVITY JT.

A

NO

17
Q

STATE 2 TYPES OF CARTILAGINOUS JT.

A
  1. PRIMARY CARTILAGINOUS (SYNCHONDROSIS)
  2. SECONDARY CARTILAGINOUS (SYMPYSIS)
18
Q

STATE THE CHARACTERISTICS OF SYNCHONDROSIS ALONG WITH THE EXAMPLES.

A
  • SYNCHONDROSIS IS THE PRIMARY CARTILAGINOUS JT.
  • IT IS WHERE THE BONE IS UNITED BY THE CARTILAGE WHICH IS HYALINE CARTILAGE.
  • IT IS IMMOVABLE
  • IT IS LOCATED BETWEEN THE EPIPHYSIS AND DIAPHYSIS (AT THE EPIHYSEAL PLATE - WHICH LOCATED AT THE METAPHYSIS)
  • EXAMPLE: BETWEEN THE RIB AND STERNUM
19
Q

STATE THE CHARACTERISTICS OF SYMPHYSIS.

A
  • SYMPHYSIS IS WHERE THE ARTICULATING SURFACES ARE COVERED BY THE HYALINE CARTILAGE AND IS THEN UNITED BY THE FIBROCARTILAGE.
  • IT IS SLIGHTLY MOVABLE
  • SYMPHYSIS IS USUALLY MUCH MORE STRONGER AND STABLE.
  • IT USUALLY LOCATED AT THE MEDIAN PLAN OF THE BODY.
  • EXAMPLE: PELVIS AND INTERVERTEBRAL JOINT.
20
Q

STATE 2 EXAMPLES WHERE DOES SYMPHYSIS CAN BE FOUND.

A
  1. PELVIS
  2. INTERVERTEBRAL JT
21
Q

STATE AN EXAMPLE WHERE DOES SYNCHONDROSIS CAN BE FOUND

A

BETWEEN RIB AND STERNUM

22
Q

A. DOES SYNOVIAL JT MOVABLE?
B. WHERE CAN WE FOUND SYNOVIAL JT?
C. WHAT IS THE IMPORTANT FEATURES THAT CAN BE FOUND IN SYNOVIAL JT?

A

A. YES, SYNOVIAL JT IS MOVABLE.
B. USUALLY IN THE UPPER OR LOWER LIMB
C. - SYNOVIAL MEMBRANE
- SYNOVIAL FLUID
- ARTICULAR CARTILAGE (HYALINE)
- FIBROUS CAPSULE

23
Q

STATE THE CHARACTERISTICS OF BALL AND SOCKET.

A
  • IT CONSIST OF GLONOID HEAD INSERTED INTO THE APPOSING CUP.
  • IT IS MULTIAXIAL (FLEXION, EXTENSION, ABDUCTION, ADDUCTION, CIRCUMDUCTION, ROTATION)
  • HIP JT, SHOULDER JT
24
Q

STATE THE CHARACTERISTICS OF SADDLE JT.

A
  • SADDLE RESEMBLES THE SADDLE ON THE HORSE’S BACK
  • IT IS A CONCAVE-CONVEX SURFACE
  • IT IS BIAXIAL (FLEXION, EXTENSION, ADDUCTION, ABDUCTION)
  • EXAMPLE: CARPO- METACARPAL OF THE THUMB
25
Q

STATE THE CHARACTERISTICS OF THE HINGE JT.

A
  • HINGE JT RESEMBLES THE HINGE OF A DOOR.
  • IT IS CONVEX OPPOSE THE CONCAVE SURFACE
  • IT IS UNIAXIAL (FLEXION AND EXTENSION ONLY)
  • EXAMPLE: HUMERO- ULNAR, INTERPHALANGEAL
  • KNEE IS A MODIFIED HINGE IN WHICH IT IS A MULTIAXIAL.
26
Q

A
  • TROCHOID JT ALSO KNOWN AS PIVOT JT.
  • IT IS WHERE THE BONY PIVOT SURROUNDED BY THE BONY LIGAMENTIOUS RING
  • TROCHOID JT IS UNIAXIAL (ROTATION ONLY)
  • EXAMPLE: ATALANTO-AXIAL JT, RADIO- ULNAR JT
27

STATE THE CHARACTERITISTICS OF CONDYLOID JT.

A
  • CONDYLOID JT ALSO KNOWN AS ELLIPSOIDAL JT.
  • IT IS WHERE AN ELLIPSOIDAL CONVEX INTO THE ELLIPSOIDAL CONCAVE SURFACE.
  • IT WILL PROVIDE A BIAXIAL MOVEMENT (FLEXION, EXTENSION, ABDUCTION, ADDUCTION)
  • EXAMPLE: ATLANTO- OCCIPITAL JT, RADIO-CARPAL JT, METACARPO-PHALANGEAL JT
29
Q
