Classification Of Tissues Part 2

Front 1

Four types of tissues

Back 1

Connective, epithelial, muscle, and nervous

Front 2

Connective Tissue

Back 2

Most widely abundant

Found everywhere in the body

Four classes:

1. Connective proper

2. Cartilage

3. Bone

4. Blood

Front 3

Purpose of connective tissue

Back 3

1.Binding and support

2. Protection

3. Insulation

4. Transportation (Blood)

Front 4

Embryonic tissue that connective tissue arise from

Back 4

Mesenchyme

Front 5

Dense connective tissue

Back 5

binds bones or skeletal muscle to bone

Front 6

Regular dense connective tissue

Back 6

running in the same direction (ex. tendons)

Front 7

Irregular dense connective tissue

Back 7

running in many directions (ex. dermis)

Front 8

Loose connective tissue

Back 8

soft tissue

Front 9

Areolar loose connective tissue

Back 9

cushions body organs

Front 10

Adipose loose connective tissue

Back 10

insulation for body tissues

Front 11

Reticular loose connective tissue

Back 11

internal support system

Front 12

Cartliage

Back 12

Flexibility, shock absorbance

Front 13

Bone

Back 13

Structural

Front 14

Loose connective tissue, areolar

Back 14

Function: wraps and cushions organs

Location: widely distributed under epithelia of body.

Front 15

Loose connective tissue, adipose

Back 15

Function: Insulates against heat loss

Location: under skin

Front 16

Loose connective tissue, reticular

Back 16

Function: fibers form stroma that supports other cell types

Location: Lymphoid organs

Front 17

Dense connective tissue, regular

Back 17

Function: attaches muscles to bones or to muscles

Location: Tendons

Front 18

Dense connective tissue, elastic

Back 18

Function: allows recoil of tissue following stretching

Location: walls of large arteries

Front 19

Dense connective tissue, irregular

Back 19

Function: Provides structural strength

Location: Dermis of the skin

Front 20

Cartilage: Hyaline

Back 20

Function: supports and reinforces

Location: Forms costal cartilages of the ribs

Front 21

Cartilage: Elastic

Back 21

Function: maintains the shape of structure while allowing great flexibility

Location: Supports external ear (pinna)

Front 22

Cartilage: Fibrocartilage

Back 22

Function: tensile strength with the ability to absorb compressive shock

Location: Intervertebral discs

Front 23

Bones (Osseous Tissue)

Back 23

Function: supports and protects

Location: Bones

Front 24

Blood

Back 24

Function: Transport of respiratory gases

Location: Blood vessels

Front 25

Nervous Tissue

Back 25

Two major cells:

1. Neuroglia: support and insulates neurons

2. Neurons: highly specialized to receive stimuli and conduct impulses

Front 26

Nervous Tissue

Back 26

Function: transmit electrical signals from sensory receptors and to effectors which control their activity.

Location: Brain, spinal cord, nerves

Front 27

Muscle Tissue

Back 27

Three types:

1. Skeletal

2. Cardiac

3. Smooth

Front 28

Skeletal muscle

Back 28

Function: Facial expressions

Location: In skeletal muscles attached to bones

Front 29

Cardiac muscle

Back 29

Function: As it contracts, it propels blood into the circulation

Location: The walls of the heart

Front 30

Smooth muscle

Back 30

Function: Propels substances or objects along internal passageways

Location: Mostly in walls of hollow organs
