Question | Answer |
Classification of Bones by Region: bones of the skull, vertebral column, and rib cage. | Axial skeleton |
bones of the upper and lower limbs, shoulder, and hip. | Appendicular skeleton |
Contains no blood vessels or nervesSurrounded by the perichondrium (dense irregular connective tissue) that resists outward expansion | Skeletal Cartilages |
Provides support, flexibility, and resilienceIs the most abundant skeletal cartilage | Hyaline Cartilage |
Found in the external ear and the epiglottis | Elastic Cartilage |
Highly compressed with great tensile strengthContains collagen fibers.Found in menisci of the knee and in intervertebral discs | Fibrocartilage |
Thin layer of hyaline cartilage. Reduces friction at joints | Articular cartilage |
Lines internal surfaces of bone. Surrounds medullary cavity | Endosteum |
Dense irregular connective tissue | Periosteum |
unspecialized stem cells | Osteogenic cells |
synthesize & secrete collagen | Osteoblasts |
mature bone cells | Osteocytes |
digest bone matrix | Osteoclasts |
weight-bearing, column-like matrix tubes composed mainly of collagen | Lamella |
connecting blood and nerve supply of the periosteum to that of the Haversian canal | Perforating or Volkmanns canals |
small cavities containing osteocytes | Lacunae |
canals that connect lacunae | Canaliculi |
The____ _____ is the site of long bone growth | epiphyseal plate |
Factors Affecting Bone Growth | Growth Hormone IGFs Thyroid hormone and insulin,Sex steroids Calcitonin and Parathyroid hormone |
Lateral bending of vertebral column | Scoliosis |
Increase in the thoracic curve of the vertebral column | Kyphosis |
Increase in the lumbar curve of the vertebral column | Lordosis |
A genetic bone disorder, also known as “brittle bone disease” | Osteogenesis Imperfecta |
Bone resorption outpaces bone development Can be due to calcium loss. Bone mass becomes so depleted that fractures can occur spontaneously | Osteoporosis |
