Animal Tissue
Epithelial CellConsists of a
single layer of cells covering the surface of our body and the organs within it.
Structurally we may group the cells squamous or flat, cuboidal, columnar, ciliated , or flagelatted.
A simple squamousepithelium is made up of thin flat cells.
Stratified squamousepithelium
Forms the outer layer of the skin
Cuboidalepithelium Cube like cells, is presented in our salivary glands, kidney tubules and thyroid gland.
Stratified columnar epithelium
Consists of cells that are tail or elongated
CilaitedCellHas on its exposed sureface, numerous short hairlike extension known as cilia.
Columnar ciliated epitheliumLines the air
passages of land vertebrates
GlandullarEpitheliumSpecializes in secreting products needed by the body. Our sebaceous and salivary glands are lined with cuboidal cells
The epithelial cell that specialize in receiving certain kinds of external stimuli are called sensory cell.
The most common types of connective tissues are fibrous, cartilage, bone, adipose and, vascular tissues.
Fibrous TissuesIs the most
common type of connective tissue found all over our body.
Cartilage Tissue
Secrete fibrous materials that are strong but flexible.
The other parts of our body with cartilage are our larynx and intervertebral discs.
Bone TissueIs much harder
than our cartilage tissue. It formed by stellate cells osteoblasts.
The dead, hard materials of bone is mainly calcium phosphate.
Adipose Tissue Is a special type of
supporting tissue.
Serve s as fat storage and as supporting pads for other tissues.
Each adipose tissue cell is characterized by the presence of fat droplets or globules.
Vascular Tissue Our body is the vascular or
circulatory tissue of our body.
It is also a tissue that consists of a fluid component, the plasma and the cellular parts.
The plasma diffuses out of a capillary into spaces between cells and becomes part of our lymph.
The cellular part consists of the red blood cell or erythrocytes.
The white blood cell or leukocytes.
Small cell fragment called blood platelets or thrombocytes.
Muscular pr Contractile Tissue
The different kinds of muscle tissues are smooth, striated and cardiac
Smooth Muscle Also called involuntary
muscle, consist of delicate spindle shaped cells, each with one central oval nucleus and homogeneous fibrils.
Because it is found in the internal organs, it is likewise called visceral muscle.
Striated Muscles Are also called skeletal
muscle, because they are attached to our bones. Their movement can be controlled at will; thus they also called voluntary muscles.
Heart muscle Is called the cardiac
muscle
The cardiac muscle is striated yet involuntary. Its movement is not controlled at will.
Nervous tissue The simultaneous use of
your senses is possible because you have a nervous system which is composed of nerve cells or neurons.
