1. The suppose axes of the human body are?
2. The sections or planes of the human body on the basis of the axis?
3. Which types of the development of the bone?(membranous and cartilaginous ossification)
4.The characteristics of the long bone?
5. Which bone exists the red marrow in life?
6. The periosteum (Endosteum) are two layers (outer is the fibrous and inner the membrenous )(Osteoblast,Osteoclast)
Superior costal fossa
The thoracic vertebra
1.Thoracic vertebrae: costal facets on each side of their body
2. The cervical vertebrae: transverse foramen.
Atlas: Anterior arch and posterior arch and a lateral mass.
Fovea dentis, groove for vertebral artery.
Axis: dens or odontoid process
Vertebra prominens: nonbifid spine is long and easily felt.
3. Lumbar vertebrae: The spines are strong, square and horizontal
4. sacrum: It is made up of five fused vertebrae and roughly triangular. There are three surfaces
Promontory of sacrum, anterior and posterior foramina, lateral masses, ala, median sacral crest, intermediate and lateral crests
Dorsal sacral foramina, sacral canal, sacral hiatus, sacral cornu or horns, auricular
surface, sacral tuberosity.
5. coccyx: It is made up of four, more or less, coccygeal vertebrae
Those include the bone of the arm, the bones of the forearm and the bones of hand (the carpal bones, metacarpal bones and phalanges)
The bone of arm
is the longest and largest bone of the upper limb. It extends from the scapula to
the elbow joint and has a body and two ends
The radius is the lateral bone of the two in the forearm. It has a shaft and two ends.
The proximal end
A head, neck and tuberosity;
head is disc-shaped and its upper surface is a shallow cup—articular fovea for articulation with the capitulum of the humerus. Its articular circumference articulates with radial notch of the ulna.
Shaft of radius: interosseous border
Ulnar notch, styloid process, carpal articular surface
is formed by a hip bone on each side.
They articulate posteriorly with the sacrum and meet below and in front at the pubic symphysis
Bony pelvis =the pelvis girdle
