1 Skeletal System Chapter Overview of the skeletal system What are the functions of the skeletal system? 1. Supports the body 2. Protects the soft body parts 3. Produces blood cells 4. Stores minerals (calcium and phosphate) and fat 5. Allows for movement by attaching muscles 11.1 Overview of the skeletal system What is the anatomy of a long bone? Diaphysis shaft of the bone made of compact bone and filled with yellow marrow Epiphysis ends of the bone made mostly of spongy bone Articular cartilage hyaline cartilage found on the ends of long bones Yellow bone marrow stores fat Red bone marrow makes blood cells found in spongy bone and flat bones Periosteum living, outer covering of fibrous connective tissue Ligaments fibrous connective tissue that connects bones 11.1 Overview of the skeletal system More detail on bone Compact bone Composed of osteons with a central canal containing blood vessels Contains living bone cells called osteocytes chambers called lacunae Spongy bone Made of plates with spaces filled with red bone marrow 1

2 11.1 Overview of the skeletal system Where are the 3 types of cartilage found? Cartilage flexible connective tissue categorized based on the type and arrangement of matrix fibers Types: Hyaline cartilage ends of long bones, nose, ends of ribs, larynx and trachea Fibrocartilage disks between vertebrae and in the knee; stronger than hyaline cartilage Elastic cartilage ear flaps and epiglottis; more flexible than hyaline cartilage What are the important cells in bone growth, remodeling and repair? Osteoblasts bone-forming cells Osteocytes mature bone cells that maintain bone structure derived from osteoblasts Osteoclasts bone-absorbing cells How does bone develop? Ossification - the formation of bone in two distinct ways: 1. Intramembranous ossification - bone development between sheets of fibrous connective tissue; used in flat bones 2. Endochondrial ossification cartilage is replaced by bone; used by most bones How does endochondral ossification occur? 1 st Cartilage model chondrocytes lay down hyaline cartilage in the shape of the future bones 2 nd Bone collar formation osteoblasts secrete bone matrix and results in a collar made of compact bone 3 rd Primary ossification center osteoblasts are brought interiorly by blood and lay down spongy bone 4 th Secondary ossification sites bone centers in the epiphyses formed after birth 5 th Epiphyseal plate a cartilage band that acts as a growth plate that allows bones to lengthen 2

3 Visualizing endochondral ossification How do bones lengthen? How do hormones affect bone growth? Growth hormone (GH) stimulates general bone growth and the epiphyseal plates Sex hormones increases growth during adolescence Vitamin D converted to a hormone to allow calcium absorption in the intestine What is bone remodeling and what is its role in homeostasis? Bone remodeling bone renewal at a rate of up to 18% per year Remodeling allows bones to respond to stress Regulates the calcium in the blood through hormones: Parathyroid hormone (PTH) increases blood calcium by accelerating bone recycling Calcitonin decreases blood calcium 3

4 Health focus: Osteoporosis Osteoporosis bones are weakened due to a decreased bone mass Bone reabsorption exceeds absorption usually by age 40 Risk factors: women, white or Asian, thin, family history, early menopause, smoking, diet low in calcium, excessive caffeine or alcohol consumption and a sedentary lifestyle Can lead to fractures and other complications Can be treated with drugs, hormones and lifestyle change Steps in bone repair Hematoma (6-8 hrs.) blood clot formed between broken bones Fibrocartilaginous callus (~ 3 weeks) cartilaginous callus forms between broken bones Bony callus (3-4 months) cartilaginous callus is turned to bone Remodeling old bone tissue is replaced by new bone tissue Bone repair The 206 bones of the skeleton 4

5 The axial skeleton Skull made of cranium and facial bones Hyoid bone Vertebral column vertebrae and intervertebral disks The skull the cranium Cranium Protects the brain Composed of 8 bones Some contain sinuses Rib cage ribs and sternum Bones of the face and the hyoid bone Facial bones Mandible Maxillae Zygomatic bones Nasal bones Hyoid Only bone that does not articulate with another bone The vertebral column Types of vertebrae 33 vertebrae Cervical (7) Thoracic (12) Lumbar (5) Sacrum (5 fused) Coccyx (4 fused into tailbone) Intervertebral disks Fibrocartilage between vertebrae 5

6 Ribs protects heart and lungs Flattened bone originating from the thoracic vertebrae 12 pairs: 7 pr. true ribs 3 pr. false ribs 2 pr. floating ribs The rib cage 11.4 Bones of the appendicular skeleton The appendicular skeleton Pectoral girdle Scapula and clavicle Upper limb Arm and hand bones Sternum Known as the breastbone 11.4 Bones of the appendicular skeleton Pelvic girdle coxal bone The appendicular skeleton Lower limb Leg and foot bones 11.5 Articulations Types of joints (where bones meet bones) Fibrous usually immovable such as the sutures between cranial bones Cartilaginous tend to be slightly movable such as the intervertebral disks Synovial freely movable joints such as the ball-and-socket hip and shoulder joints and the knee joint 6

7 11.5 Articulations Anatomy of a synovial joint 11.5 Articulations Summary of synovial joints movements Flexion decrease in joint angle Extension - increase in joint angle Adduction body part moves toward midline Abduction body part moves away from midline Inversion sole of foot turns inward Eversion sole of foot turns outward 11.5 Articulations Visualizing synovial joints movements 7
