ZOOL 3214 1st Edition Lecture 121. Histology- Connective Tissue (CT)- Fibrous- Supportive- Fluid - Cartilage (like bone)- A supportive CT matrix- Ground substance: sulfate-loosed- Fibers: elastin- Cells: chondrocytesA. Hyaline Cartilage- Costal Cartilage- Articulated Cartilage- Nasal SeptumB. Fibrocartilage- Intervertebral Discs- Pubic SymphosisC. Elastic Cartilage- External Ears (piercing)- Epiglottis(Cartilage: No BV, nutrition, waste, oxygen, etc. through diffusion)2. Types of Joints- Arthology: study of joints- Joints: referred to as (Articulation)- Kinesiology: study of movement (bones, muscles, joints, ligaments)- APR & Lab: movement terms -ex. Supination & pronation-adduction & abduction-elevation & depressionA. Bony Joints- 2 or more bones fuse/ossify into 1 bone during development (frontal bone & mandible)- Childhood into early adulthood (hipbone: ilium, ischium, and pubis)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.B. Fibrous Joints1. Sutures: fibrous (stitches) that bring together the flat bones in the skull (recall newborns: still quite flexible)*Can produce sutural bones2. Gomphoses: anchor teeth to Alveolar Processes in the tooth sockets2. Syndesmoses: sheets of fibrous CT (ex. Interosseous membranes between tibia & fibula)C. Cartilaginous Joints1. Synchondroses- Ex. Epiphyseal plates- @ true regions of growth @ ends of long bones: hyaline cartilage- w/ growth cartilage is replaced by bone - Children: you can see the epiphyseal growth plate- Adults: see epiphyseal lines2. Symphyses- Ex. Pubic symphysis (Fibrocartilage) & IV DiscsD. Synovial Joints: Lab, APR, & Text- Categorized by range/form of movement- Ex. Ball & socket or
