Structure and Function in Animal Tissues

Dice-shaped cells specialized for secretion, makes up the epithelium of kidney tubules and many glands.

Cuboidal epithelium

Brick-shaped cells are often found where secretion or active absorption is important.

Simple columnar epithelium

The single layer of plate like cells functions in the exchange of material by diffusion.

Simple squamous epithelium

A single layer of cells varying in height and the position of their nuclei which forms a mucous membrane that lines portions of the respiratory tract, sweep the film of mucus along the surface.

Pseudostratified columnar epithelium

Binds epithelia to underlying tissues and holds organs in place.

Loose connective tissue

found in tendons attach muscles to bones, and in ligaments, which connect bones at joints

Fibrous connective tissue

a mineralized connective tissue including repeating units called osteons in mammal. Osteons have concentric layers of the mineralized matrix, which are deposited around a central canal containing blood vessels and nerves.

Bone

Pads and insulates the body and stores fuel as fat molecules

Adipose tissue

Carry oxygen, white cells function in defense, and platelets aid in clotting.

Blood

• a strong and flexible support material

• secrete the collagen and chondroitin sulfate, which together make ___ a strong yet flexible support material.

• skeletons of many vertebrate embryos contain cartilage that is replaced by bone as the embryo matures

• act as cushions between vertebrae

Cartilage

Provide strength and flexibility

Collagenous fibers

Where collagenous fiber can be found ?

Tendon, ligament, skin, cornea, cartilage, bone, blood vessels, gut, and intervertebral disc.

Stretch and snap back to their original length

Elastic fibers

Where elastic fiber can be found ?

Extracellular matrix

Join connective tissue to adjacent tissues

Reticular fibers

Where reticular fibers can be found ?

liver, bone marrow, lymphatic organs

striated muscle, is responsible for voluntary movement

Skeletal muscle

responsible for involuntary body activities

Smooth muscle

responsible for contraction of the heart

Cardiac muscle

transmit nerve impulses

Neurons

or glia, that help nourish, insulate, and replenish neurons

Glial cells
