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
Define amphiarthroses
Slightly movable joints
Define diathroses
Freely movable joints
Functional classification of most synovial joints?
Diarthroses
Temporomandibular joint
Temporal and Mandible
Sternoclavicular joint
Sternum and Clavicle
Humeroscapular/ Glenohumeral joint

Flexion
Decreases angle between articulating bones in the anterior/posterior plane
Extention
Increases angle between articulating bones in the anterior/posterior plane
Dorsiflexion
Flexion at ankle
Plantar flexion
Extension at ankle
Hyperextention
Extension past anatomical position
Abduction
Movement away from the longitudinal axis
Adduction
Movement towards the longitudinal axis
Pronation
Results in palm facing posteriorly, radius and ulna
Supination
Results in palm facing anteriorly, forearm is supinated in anatomical position
Circumduction
A complete circular movement without rotation
Protraction
Anterior movement in the horizontal plane (forward)
Retraction
Pulling back
Condyle
A large, rounded, articulating knob
Facet
A flattened or shallow articulating surface (the costal facet of a thoracic vertebra)
Head
A prominent, rounded, articulating end of a bone (the head of the femur)
Crest
A narrow, ridgelike projection (the iliac crest of the os coxa)
Epicondyle
A projection above a condyle (the medial epicondyle of the femur)
Process
Any marked, bony prominence (the mastoid process of the temporal bone)
Spine
A sharp, slender process (Spine of the scapula)
Trochanter
A massive process found only in the femur
Tubercle
A small rounded process
Tuberosity

A deep pit or socket (teeth)
Fissure
A narrow, slit-like opening (the superior orbital fissure of the sphenoid bone)
Foramen
A rounded opening through the bone
Fossa
A flattened or shallow surface
Meatus/Canal
A tube-like passageway through a bone
Sinus
A cavity or hollow space in a bone
Sulcus
A groove that accommodates a vessel, nerve, or tendon
Diffusion
Movement of material across cell membrane
Active transport
Requires E, goes against gradient
Endocytosis
Intake of materials
Exocytosis
Removal of materials
Facilitated diffusion
Requires carries due to size
Passive diffusion
No E
Free energy
Capacity of a system to do work
Entropy
Disorder
Osmosis
Diffusion of water through selectively permeable membrane
Solutions
Liquid mixture of solute and solvent
Isosmotic
No net movement of water
Hypoosmotic
Solution with lower solute concentration, higher water conc.
Hyperosmotic
Solute with higher solute conc, lower water conc.
Osmotic Pressure
Measure of the force necessary to resist osmosis of pure water in a solution
Colligative property
Dependent on only the number of particles present, not their type
Carrier protein
Inside of membrane, used for active transport
How to calculate percent solution
(Mass of solute / Mass of solution)* 100
How to calculate molar concentration
Molar Conc = Moles of solute/ L of solution
How to calculate moles of solution
Mass of solute / Molar mass of solute
Effect of temperature on diffusion rate
Particles at higher temp have more kinetic E so they diffuse faster
