Exercise 6: Tissues

Front 1

Embryonic Connective Tissue: Mesenchyme

Back 1

Function: Gives rise to all other connective tissue types Location: Primarily in embryo

Front 2

Areolar: Loose connective tissue

Back 2

Function: Wraps and cushions organs Location: Distributed under epithelia, packages organs; surrounds capillaries

Front 3

Adipose: Loose connective tissue

Back 3

Function: Provides reserve fuel, insulation, supports and protects organs Location: Underskin, around kidneys and eyeballs, abdomen and breast

Front 4

Reticular: Loose connective tissue

Back 4

Function: Fibers form soft internal skeleton that supports other cell types Location: Lymphoid organs

Front 5

Dense Regular: dense connective tissue

Back 5

Function: Attaches muscles to bones or to muscles; attaches bones to bones Location: Tendons and most ligament

Front 6

Elastic: dense connective tissue

Back 6

Function: Allows recoil of tissue following stretching; maintains pulsatile flow of blood through arteries; aids in passive recoil of the lungs Location: Walls of large arteries and bronchial tubes

Front 7

Dense Irregular: dense connective tissue

Back 7

Function: Able to withstand tension exerted in many directions; provides structural strength Location: Fibrous capsules of organs and of joints; dermin of the skin; submucosa of digestive tract

Front 8

Hyaline: Cartilage

Back 8

Function: Supports and reinforces; has resilient cushioning properties; resists compressive stress Location: Forms most of the embryonic skeleton; forms costal cartilage, nose, trachea and larynx

Front 9

Elastic: Cartilage

Back 9

Function: Maintains the shape of a structure while allowing great flexibility Location: Supports the external ear

Front 10

Fibrocartilage: Cartilage

Back 10

Function: Tensile strength with the ability to absorb compressive shock Location: Intervertebral discs; pubic symphysis; discs of knee joint

Front 11

Osseous Tissue: Bones

Back 11

Function: Supports and protects; provides levers for the muscles to act on; marrow is site of blood formation Location: Bone

Front 12

Blood

Back 12

Function: Transport of respiratory gases, nutrients, wastes, and other substances Location: Contained within blood vessels

Front 13

Nervous Tissue

Back 13

Function: Transmit electrical signals from sensory receptors and to effectors Location: Brain, spinal cord, nerves

Front 14

Skeletal Muscle

Back 14

Function: Voluntary movement; locomotion; manipulation of the enviroment Location: In skeletal muscles attached to bones or occasionally skin

Front 15

Cardiac Muscle

Back 15

Function: As it contracts, it propels blood into the circulation; involuntary control Location: Walls of the Heart

Front 16

Smooth Muscle

Back 16

Function: Propels substances or objects along internal passageways; involuntary control Location: Mostly in the walls of hollow organs
