JointsJoint forms the junction of two or more bonesThere are three types of joints;Immovable (fixed) jointsSlightly movable jointsMovable joints
Слайды и текст этой презентации
Слайд 3Immovable Joints
It can not move
All cranial and facial bones (skull)
are immovable
Lower part of vertebral column
Слайд 4Slightly Movable Joints
They can move slightly
Vertebrae and thoracic joints are
slightly movable
Separated by cartilage
Слайд 5Movable Joints
The bones in movable joints are connected to each
other by ligaments (very strong connective tissue fibers)
There is a
synovial fluid and cartilage in movable joints which reduces friction
Слайд 11Skull (22)
It has 22 bones
Cranial bones (8)
Facial bones (14)
Cranial bones
are fused to each other by immovable joints and enclose
important nerve centers
Слайд 12Thorax
The bones of thorax are composed of the vertebral column,
sternum, ribs, pelvic girdle and pectoral girdle
Слайд 13Vertebral column
Protects spinal cord
All vertebrae are involved in the movement
of backbone
Atlas and axis (first two) are involved in head
movement
Слайд 14intervertebral
disks
cervical vertebrae (7)
thoracic vertebrae (12)
lumbar vertebrae (5)
sacrum (5 fused)
coccyx (4
fused)

Слайд 15Thorax
Also named as chest
Protects heart, lungs and other abdominal organs
Consists
of ribs(12 pairs) and sternum
Слайд 18Extremities
They consist of
- arms + hands
- legs + feet
Each
arm and leg have 3 bones
Each foot and hand have
27 bonesTotal bones in extremites is 120
