The SkeletonWe also discuss several other topics like Where is the layer cake federalism based on?
- Articulated: bones are joined together
- Disarticulated: bones are not joined
Types of Bones
- Long
- Short
- Flat
- Irregular
- Sesamoid
- Sutural
Anatomy of Long Bone
- Proximal and distal epiphysis
- Diaphysis (shaft of bone, “dia” = inbetween)
- Metaphysis (transition between diaphysis and epiphysis)
- Epiphysis and metaphysis are made up of spongy bone and filled with red marrow
- Diaphysis made up of compact bone
- Inside of diaphysis, there is a cavity called the medullary cavity
- In adults, the cavity is filled with fat or yellow bone marrow
- For protection, bone is covered with a dense, regular tissue called periosteum on the outside
- On the inside, there is endosteum
- Periosteum has 2 layers: fibrous on outside layer and cellular on inside
- Endosteum is made of one layer but had different cells
- Osteoprogenitor: gives rise to all cells
- Osteoblasts: building new bone
- Osteocyte: maintain bone matrix
- Osteoclast: destroy bone using lysosomes and enzymes
Formation of Bone
- Endochondral ossification is how long bones form
- Bones begin as hyaline cartilage
- Ossification begins in diaphysis (center)
- Secondary ossification centers are in epiphysis
- As ossification continues, hyaline cartilage remains in the metaphysis; these are growth plates
- Intramembranous ossification is how flat bone form

Axial Skeleton
- Bones forming central axis of skeleton
- Provides main support
- protect s central nervous system
- Skull
- Thoracic cage
- Sternum and ribs
- Vertebral
Appendicular Skeleton
- Shoulder clavicle and scapula
- Upper limb
- Pelvic girdle
- Lower limb
The Skull
- Superior, lateral, posterior
- Frontal, parietal(2), occipital, temporal(2), sphenoid, ethmoid
Facial Bones
- Anterior bones, face
- Nasal, maxillary, zygomatic, mandible, lacrimal (means tear)
Process = Projection
- From an inferior perspective, the temporal bone juts inward, this is called the petrous portion. These is also a depression called the mandibular fossa
- Occipital bone has a hole at the bottom: foramen magnum
- The mandible and maxillary have an alveolar process (depression)
- Palate is made up of maxillary bone
- At end of palate are palatine bones
- Within the sphenoid bone there is a depression called sella turcica which holds the pituitary gland
- Sphenoid sinus - cavity within sphenoid
- Aids in sound resonation
- Makes skull lighter
- From a mid - sagittal view, the vomer bone is visible, which forms the bottom of the nasal septum
- The rest of the nasal bone is made up of ethmoid bone
- The perpendicular plate
- Crista galli

Suture = connects bones of skull
- Coronal suture - between frontal and parietal
- Sagittal suture - between left and right parietal bones
- Squamous portion of maxillary bone
- Lambdoid suture - between parietal and occipital bones
Vertebral regions:
- Cervical(7) - number of vertebrae
- Thoracic(12)
- Lumbar(5)
- Sacral(5)
- Coccygeal(3-5)
A typical vertebra has the body (bulky region) and an arch
- A pedicle connects body to arch
- Lamind connects left and right arch
- Opening in vertebrae = vertebral foramen
- Spinous process: projects out
- transverse process: projects on the sides
- Cervical vertebrae have transverse foramen (openings on sides)
- C1 is called Atlas: holds the Skull
- C2 is called Axis: allows for rotation of the atlas
- Within body of C2 is a projection called “dens”
- Articular processes allow for movement between vertebrae
