Cartilage (Chondro)

Tough, but flexible tissue, can withstand considerable degree of pressure and shearing forces, avascular, slow healing repair rate

Hyaline Cartilage

Most common, supprt reinforcement, cushioning, resist compressive forces, growth of long bones
Ex- larynx, trachea, bronchi, ends of ribs, joint surfaces (articular cartilage), nasal septum, epiphyseal plate, embryonic skeleton

Elastic Cartilage

Elastic fibers and characteristics, flexible, maintains shape
Ex- external ear, epiglottis

Fibrocartilage

Shock absorber, firm support with tensile strength
Ex- inervertebral discs, manubriosternal joint, TMJ, meniscus

Perichondrium

Dense irregular connective tissue, helps nourish cartilage, creates new cartilage along surface, found around all cartilage except articular cartilage

Functions Bone

Protect vital organs, support/framework of body, shock absorption, provides movement, hematopoiesis, storage for mineral salts

Bone tissue components

Inorganic-mineral salts
Organic matrix- consits of collagen fibers, proteoglycans, glycoproteins,
Highly vascularized
Dynamic tissue continuously being reorganized

Osteon

Structural unit of compact bone, parallel to long axis of bone

Lamellae

concentric layers of bone matrix, collagen fibers run in same direction for each lamella

Osteocytes

Bone cells within matrix, maintain health of bone

Central Canal

Blood vessels and nerves

Periosteum

Dense, irregular connective tissue, surrounds bones, nourish external protion of bones, provides attachment for tendons and ligaments

Long Bone

longer than wide, ie humerus

Short BOne

cuboidal shape, ie carpals

Flat Bone

Protection, ie ribs, skull, sternum

Irregular Bone

unusual shpae, ie vertebra, scapula

Sesamoid Bone

Bone within tendon, ie patella

Axial Skeleton

Skull, vertebral column, thorax

Appendicular Skeleton

Upper and lower extremities, pectoral and pelvic girdles

Fibrous Joints

NO joint capsule, joint cavity
Bones come together held together with seam, sheet connective tissue
Ex- Suture (skull), Syndesmosis, Gomphosis

Cartilaginous Joints

NO joint capsule, joint cavity
Primary (synchondrosis)- bar or plate of hyaline cartilae unites bones
Secondary (symphysis)- fibrocartilage between joints

Synovial Joints

Joint capsule, joint cavity, most movement overall, MOST common, fluid filled vaity, fibrous capsule
Ex- Plane, Hinge, Saddle, Condyloid, Ball and Socket, Pivot (named by how look)

Skeletal Muscle

...

Cardiac Muscle

...

Smooth Muscle

...

Fascicles

Bundle of skeletal muscle fibers, arrangement of fascicles determines shape and function of skeletal muscles
Ex- parallel, pennate, triangular, convergent, quadrate, circular
