Study Notes
Functions of the Skeletal System
- Provides support for the body, acting as an internal framework for organs.
- Offers protection for internal organs.
- Enables movement through the interaction of skeletal muscles and bones.
- Serves as a storage site for essential minerals (calcium, phosphorus) and fat.
- Facilitates blood cell formation (hematopoiesis) within the red bone marrow.
Classification of Bones
- An adult human skeleton consists of 206 bones, varying in size and shape.
- Long bones are composed of compact and spongy bone, providing strength, structure, and mobility.
Gross Anatomy of the Bone
- The long bone structure includes two main parts: the diaphysis and the epiphysis.
Axial Skeleton
- Formed by 22 bones, including 8 cranial flat bones and 14 facial bones.
- Includes 3 small bones in the middle ear of each side and 1 hyoid bone.
Cranium (8 Bones)
- The cranial bones form the braincase, protecting the brain, eyes, and ears.
Sutures
- Immovable joints between cranial bones.
- Interlocking edges prevent sliding or shifting of bones during impacts or pressure.
Paranasal Sinuses
- Air cavities located in the maxillae, frontal, sphenoid, and ethmoid bones.
- Open into the nasal cavities and lined with ciliated epithelium, continuous with the nasal mucosa.
- Functions:
- Make the skull lighter
- Provide resonance for the voice
Foramen Magnum
- A large oval opening in the occipital bone of the skull.
- Allows passage of the spinal cord from the brain.
