Living Anatomy Ch 1 & 2

Front 1

Tuberosity

Back 1

An obvious lump on a bone that serves as a site for muscle attachment.

Front 2

Tubercle

Back 2

An obvious lump on a bone that serves as a site for muscle attachment

Front 3

Uniaxial Joint

Back 3

Movement occurs in one axis or plane
Ex. knee (hinge joint), proximal radioulnar (pivot joint)

Front 4

Triaxial Joint

Back 4

Movement about 3 axes or planes. Ex. Hip (ball & socket)

Front 5

3 Forms of Muscle tissue

Back 5

Skeletal - striated, joint movement, voluntary(Biceps brachii)

Smooth - Non striated, involuntary (intestines)

Cardiac - Involuntary. Interconnected in networks that work as a unit (heart)

Front 6

Articular Cartilage

Back 6

Lines terminal portion of epiphysis where bone meets bone. Reduces wear, provides smooth articulation.

Front 7

Articular Surface

Back 7

Communicating bone surface

Front 8

Articulation

Back 8

Communication (junction) of two or more bones as they form a joint. May or may not touch.

Front 9

Biaxial Joint

Back 9

Movement about 2 axes or planes. Ex. wrist (condyloid jt)

Front 10

Bursae

Back 10

Liquid-filled membranes.
Protect soft tissues as they pass bony projections

Front 11

Cancellous Bone

Back 11

Spongy bone
Found toward the epiphysis, honeycombed or lattice

Absorbs stress and conserves weight

Front 12

Cartilaginous Joints

Back 12

Stable and provides movement
Occupies space btwn bones
Provides shock absorption,
Reduces wear & tear (spine)

Front 13

Compact Bone

Back 13

Hard bone of the diaphysis, deposited in layers.
Canals that allow nerves, lymph, and blood vessels access to inner bone tissue

Front 14

Condyles

Back 14

The articular surfaces of the bone

Front 15

Diaphysis

Back 15

Bone shaft
Made of hard compact bone w/central medullary canal.

Front 16

Epiphyseal Plate

Back 16

A cartilaginous place
Between epiphysis and diaphysis
Growth occurs here

Front 17

Epiphysis

Back 17

End of a long bone, made chiefly of cancellous bone.

Front 18

Fibrocartilage

Back 18

Shock absorption
Forms articular surface.
No blood supply of its own
Relies on synovial fluid for nurishment

Front 19

Fibrous or Sutured Joints

Back 19

Very stable with no observable movement. (The least amount of movement.

Front 20

Foramen

Back 20

A hole that passes completely through a bone

Front 21

Fossa

Back 21

Hollowed are of a bone

or hollow surface area on the body

Front 22

Joint Capsule

Back 22

Tough fibrous sheet surrounding many joints
Protects & stabilizes

Front 23

Joints

Back 23

Articulation of two or more connecting bones
Limited by ligaments, soft tissues, and joint architecture

Front 24

Ligaments

Back 24

Bone to Bone connective tissue

Front 25

Medullary Cavity

Back 25

Hollow chamber surrounded by compact bone
Contains marrow important for red blood cell formation and fat cell storage.

Front 26

Nonaxial Joint

Back 26

Involves a sliding rather than a rotating motion.
Does not move about any axis. Ex. Btwn bones of the wrist

Front 27

Notch

Back 27

Pathway for nerves or vessels

Front 28

Periosteum

Back 28

Fibrous sheath around the bone, provides nourishment and a site for developing bone cells

Front 29

Process

Back 29

Obvious lumb
site for muscle attachment

Front 30

Spine

Back 30

Bone projection - generally longer and thinner than a tuberosity.

Front 31

Synovial Joint Classification

Back 31

By the number of axes about which they rotate or the number of planes within which they move, & type of architecture (ball & socket)

Front 32

Synovial Joints

Back 32

Freely moving. Have space btwn the articular surface of the bones forming the joint, wide range of motion.

Front 33

Synovial Membrane

Back 33

Thin tissue that surrounds most freely moving joints
Nurishment for cartilaginous disks
Lubrication
Hydrostatic cushioning

Front 34

Tendons

Back 34

Muscle to Bone
