Study Notes
Skeletal System Functions
- Protection of internal organs is crucial in situations like car accidents.
- Bone tissue is dense, hard connective tissue integral to the skeletal system.
Bone Marrow and Blood Production
- Red marrow is essential for blood cell production; its absence halts this function.
- Yellow marrow serves as a fat storage area.
Types of Bones
- The skeletal system consists of bones and cartilage.
- Long bones dominate the skeleton; however, the bones in the wrist are considered short bones.
- Sesamoid bones are embedded within tendons.
Bone Classifications
- Irregular bones protect the spinal cord, while long bones facilitate movement by acting as levers.
- Cancellous bone is where hematopoiesis occurs, and trabeculae are only found in this area.
Bone Structure and Development
- Diaphysis contains fat stores; periosteum is the fibrous membrane covering bone surfaces.
- Osteoblasts and osteocytes do not replicate due to their essential functions and origins.
Bone Growth and Repair
- Endochondral ossification leads to chondrocyte death, forming the medullary cavity.
- Intramembranous ossification primarily forms flat bones in the cranium.
- Bone growth occurs at the epiphyseal plate for length and beneath the periosteum for diameter.
Fractures and Healing Process
- Fractures can be both open and transverse, and may release fat globules from damaged yellow marrow.
- Compound fractures pierce the skin, and healing begins with spongy bone formation, shifted towards trabecular bone.
Hormonal Influence on Bones
- Wolff's law demonstrates how mechanical forces influence bone remodeling based on activity patterns.
- Calcium absorption is influenced by vitamin D, and hormonal balance is maintained by calcitonin and parathyroid hormone.
Axial Skeleton Features
- The axial skeleton supports the trunk and includes key structures such as the vertebral column and cranial bones.
- Parietal bones are part of the braincase; the lambdoid suture connects parietal and occipital bones.
Vertebral Column and Ribs
- The cervical region has seven vertebrae; primary curvatures relate to fetal development.
- True ribs articulate directly with the sternum, while endochondral ossification forms the axial skeleton.
Upper and Lower Limb Anatomy
- The shoulder involves the acromioclavicular joint; the clavicle articulates with the manubrium.
- The hip bone consists of three fused bones; ilium forms the superior part, ischial tuberosity supports body weight.
Joints Classification and Types
- Joints include amphiarthrosis between vertebrae, synarthrosis at the manubriosternal joint, and biaxial diarthrosis at the metacarpophalangeal joint.
- Synovial joints have a fluid-filled cavity, while specific types like syndesmosis connect fibula and tibia.
Bursa and Joint Functionality
- Bursae reduce friction between structures, while synovial membranes secrete lubricating fluid essential for joint function.
Motion and Range
- Ball-and-socket joints provide the widest range of motion, unlike hinge joints that allow uniaxial movement.
