Lab Practical 1 Flashcards
Simple Squamous Epithelium
one layer of flattened cells
Stratified Squamous Epithelium
More than one layer of cells attached to basement membrane. i.e. epidermis
Simple Cuboidal Epithelium
One layer, cube like cells
Simple Columnar Epithelium
Pillar shaped epithelial cells
Periosteum
Fibrous outer layer and cellular inner layer that lines bones
Diaphysis
Long part of bone
Epiphysis
Two ends of long bones
Epiphyseal Plate
Actively growing regions near the ends of long bones
Articular Cartilage
Hyaline cartilage that covers the ends of long bones (articulating surfaces)
Meniscus
Padlike cartilage in knee joint
Joint Cavity
The space between bone that is encapsulated by synovial membrane and articular cartilage
Synovial Fluid
Fluid inside of synovial joints that assists with lubrication, nutrient distribution, and shock absorbtion
What are the three types of joints? (structural classification)
Fibrous, Cartilaginous, Synovial
Types of fibrous joints?
sutures, syndesmoses, and gomphoses
Define sutures
Joints in between bones of skull, fibrous tissue ossifies in adults creating synostoses
Define syndesmoses
Junction of bones held together by ligaments ex. tibia/fibula, radius/ulna
Define gomphoses
Tooth attached to socket with periodontal ligament
Types of cartilaginous joints?
Synchondroses and Symphyses
Define synchondroses
cartilaginous joints between the shafts and the epiphyseal plates of growing long bones
Define symphyses
Pads of fibrous cartilage cushions joint ex. pubic symphysis, intervertebral joints
What are synovial joints?
Articulating bones separated by a fluid-filled cavity. Most joints are this way
Shape categories of synovial joints
Plane, condylar, ball-and-socket, hinge, saddle, pivot
Functional classifications of joints
Synarthroses, Amphiarthroses, Diarthroses
Define synarthroses
Immovable Joints
