Skeletal muscles are long, cylindrical, multinucleated cells with obvious striations.

Branching, striated, generally uninucleated cells that interdigitate at specialized junctions (intercalated disc).

As it contracts, it propels blood into the circulation (Pumps blood); involuntary control

Spindle-shaped cells with central nuclei. No striations, cells arranged closely to form sheets.

Propels substances or objects along internal passageways; involuntary control.

Mostly in the walls of hollow organs like the digestive tract, bladder, arteries, and other internal organs.

A group of cells that provide support and nourishment to the neurons.

Makes up the brain, spinal cord, and other nerves in the body.

Apical surface and basal surface

It is avascular and tissue cells are highly mitotic.

Classification based on shape -Squamous (Flattened cells), Cuboidal (cube-like cells), and Columnar (column-like cells).

Classification based on arrangement - Simple (one cell layer), Stratified (several layer of cells), Pseudostratified (single layer), and Transitional (several layers of cells and designed to stretch and return to a normal state without damage).

Classifcation based on function - Mucous membrane (secretes mucus), Glandular epithelium (forms the glands), Endothelium. (lines the interior of the circulatory vessels and heart), and Mesothelium (lines the peritoneal, pleural, and pericardial cavities and covers viscera (internal organs).

Second major type of tissue

Protection, support, binding of different body structures, transport of materials, and immunity.

Most abundant type of tissue

Specialized Connective Tissue (SCT)

Gel-like matrix with all three types of fibers;
Cells: fibroblast, macrophages, mast cells, and some white blood cells.

Wraps and cushions organs; its macrophages phagocytize bacteria; plays important role in inflammation; holds tissue fluid.

Located beneath the skin (underlies epithelial tissue); around blood vessels, muscles and nerves.

Matrix as in areolar connective tissue, but very sparse; closely packed adipocytes, or fat cells, have nucleus pushed to the side by large fat droplet.

Provides reserve food fuel; insulates against heat loss; supports and protects organs.

Located under skin in the hypodermis; around kidneys and eyeballs; within abdomen; in breasts.

Fibers form a soft internal skeleton (stroma) that supports other cell types including white blood cells, mast cells, and macrophages.

Located in lymph nodes, Bone marrow, Spleen, Liver

Parallel arrangement of fibers (it has more collagen and few elastic fibers). Cells: fibroblast

Irregular arrangement of Fibers (made primarily of Collagen fibers and few elastic fibers) Cells: Fibroblast, Defense cells and fats cells may be present.

It is able to withstand tension exerted in many directions; provides structural strength.

Located in capsule surrounding the joints, dermis of the skin, outer covering of body tubes like arteries.

It can withstand TENSION when pulling force is applied in one direction.

Examples: TENDONS and LIGAMENTS, Aponeuroses and Fascia (Muscle)– TENDONS – Bone
(Bone) – LIGAMENTS – Bone

Wall of Aorta and other large arteries Wall of bronchial tubes (respiratory
passages found in the lungs).

Blood is a specialized connective tissue. Its extracellular is different from the other C.T.

The term appears clear under the microscope because the fibers are not visible.

The chondrocytes are embedded in the gel-like matrix but located within a cavity called Lacuna/Lacunae.

Located in nose, bronchi and bronchial tubes, trachea, costal cartilages (in the rib cage).

Similar to hyaline cartilage, but more elastic fibers in matrix.

Maintains the shape of a structure while allowing great flexibility.

Matrix similar to but less firm than that in hyaline cartilage; thick collagen fibers predominate.

Tensile strength with the ability to absorb compressive shock.

Located in the interrvertebral discs; pubic symphysis; discs of knee joint.
