Organs, Tissues, And Systems

Front 1

Tissue

Back 1

-coloniesor groups of cells that combine to exhibit functional unity

Front 2

Epithelial Tissue

Back 2

-1 of 4 tissue types

-superficial (outer) layer of mucous membranes and the cells constituting the skin, as well as linings of major body cavities and all of the tubes that pass into, out of, and through the body

Front 3

Connective Tissue

Back 3

-1 of 4 tissue types

-maybe solid, liquid, or gel-like; defining property is the matrix within which thecells of connective tissue are bound

Front 4

Muscle Tissue

Back 4

-1 of 4 tissue types

-specialized contractile tissue

Front 5

Nervous Tissue

Back 5

-1 of 4 tissue types

-highly specialized communicative tissue consisting of neurons (aka nerve cells)

-functions to transmit info from one neuron to another, from neurons to muscles, or from sensory receptors to other neural structures

Front 6

Vascular Tissue

Back 6

-falls under connective tissue

-blood

Front 7

Organ

Back 7

-aggregates of tissues of the body with functional unity (i.e. tissues of the organ all serve the same general purpose)

Front 8

Muscle

Back 8

-structures made up of muscular tissue

-muscles must be attached to bone or cartilage

Front 9

Fascia

Back 9

-sheet-like membrane that surrounds organs and muscles

Front 10

Ligament

Back 10

-connective tissue that binds bone to bone, bone to cartilage, and cartilage to cartilage

-most ligaments have little stretch (white ligaments), though some of elastic fibers that permit stretching (yellow ligaments)

Front 11

Tendon

Back 11

-always binds muscle to another structure (either bone, cartilage, or other muscles)

-collagenous (i.e. not elastic) fibers provide flexible structure

-very strong

Front 12

Aponeurosis

Back 12

-a sheet-like tendon

-may resemble fascia but is much denser

Front 13

Cartilage

Back 13

-connective tissue embedded in matrix

-capable of withstanding significant compressive and tensile forces (i.e. retains form against compressing forces and fibers are not easily separated when pulled)

Front 14

Articulation

Back 14

-the point of union between two structures

Front 15

Joint

Back 15

-where there is a union of bones with other bones or cartilage with cartilage

Front 16

Origin

Insertion

Back 16

Origin- the point of attachment of the least mobile element

Insertion- the point of attachment that moves as a result of muscle contraction; insertion point is more distant from the body

Front 17

Afferent

Efferent

Back 17

Afferent- nerve going to the brain carrying sensory info

Efferent- nerve going to the muscle carrying excitatory info

Front 18

System

Back 18

-groups of organs with functional unity (i.e. combination of organs performs a basic function)
