Name That Tissue, and Location, and function!

Cell processes can be quite long. Also containing nonirritable supporting cells. Transmit electrical signals from sensory receptors to effectors: muscles and glands which control their activity. Brain, spinal cord, and nerves.

Nervous Tissue

Hard, calcified matrix containing many collagen fibers; osteocytes lie in lacunae. Very well vascularized. Supports and protects; provides levers for the muscles to act on; stores calcium and other minerals and fat; marrow inside bones is the site for blood cell formation: hematopoiesis. Bones.

Osseous Tissue

Resembles both stratified squamous and stratified cuboidal; surface cells dome shaped or squamous like, depending on degree of organ stretch. Stretches readily and permits distension of urinary organ by contained urine. Lines the ureters, urinary bladder, and part of the urethra.

Transitional Epithelium

Primarily parallel collagen fibers; a few elastic fibers; major cell type is the fibroblast. Attaches muscles to bones or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction. Tendons, most ligaments, & aponeuroses.

Dense Regular Connective Tissue Proper

Primarily irregularly arranged collagen fibers; some elastic fibers; major cell type is the fibroblast. Able to withstand tension exerted in many directions; provides structural strength. Fibrous capsules of organs and of joints; dermis of the skin; submucosa of digestive tract.

Dense irregular Connective Tissue Proper

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

Adipose

Gel-like matrix with three fiber types. Wraps and cushions organs; plays important role in inflammation; holds and conveys tissue fluid. Widely distributed under epithelia of body, e.g., forms lamina propria of mucous membranes; packages organs; surrounds capillaries.

Areolar

Description: Red and white blood cells in a fluid matrix: plasma. Function: Transport of respiratory gases, nutrients, wastes, and other substances Location: Contained within blood vessels.

Blood

Description: Branching, striated, generally uninucleate cells that interdigitate at specialized junctions (intercalated discs). Function: As it contracts, it propels blood into the circulation; involuntary control. Location: The walls of the heart.

Cardiac Muscle

Description: Similar to hyaline cartilage, but more elastic fibers in matrix. Function: Maintains the shape of a structure while allowing great flexibility. Location: Supports the external ear: pinna; & epiglottis.

Elastic Cartilage

Dense tissue containing a high proportion of elastic fibers. Allows recoil of tissue following stretching; maintains pulsatile flow of blood through arteries; aids passive recoil of lungs following inspiration. Walls of large arteries; within the walls of the bronchial tubes.

Elastic Connective tissue proper

Description: Matrix similar to but less firm than that in hyaline cartilage; thick collagen fibers predominate. Function: Tensile strength with the ability to absorb compressive shock. Location: Intervertebral discs; pubic symphysis; discs of knee joint.

Fibrocartilage

Unicellular gland

Goblet cell.

Firm matrix; imperceptible collagen fibers; chondrocytes lie in lacunae. Supports and reinforces; has cushioning properties; resists compressive stress. Covers the ends of long bones in joint cavities; forms costal cartilages of the ribs; cartilages of the nose, trachea, and larynx.

Hyaline Cartilage

Single layer of cells of differing heights; nuclei seen at different levels; goblet cells, and bear cilia. Secretion, particularly of mucus; propulsion of mucus by ciliary action. Lines the trachea, most of the upper respiratory tract.

Pseudostratified Ciliated Columnar Epithelium.

Single layer of cells of differing heights; nuclei seen at different levels; goblet cells. Secretion, particularly of mucus. Male's sperm-carrying ducts and ducts of large glands.

Pseudostratified columnar epithelium.

Network of reticular fibers in a typical loose ground substance; reticular cells lie on the network. Fibers form a soft internal skeleton: stroma, that supports other cell types including white blood cells, mast cells, and macrophages. Lymphoid organs, lymph nodes, bone marrow, and spleen.

Reticular

Single layer of tall cells; bears cilia; layer may contain goblet cells. Absorption; secretion of mucus, enzymes, and other substances. Lines small bronchi, uterine tubes.

Simple Ciliated Columnar Epithelium

Single layer of tall cells; may contain goblet cells. Absorption; secretion of mucus, enzymes, and other substances. Lines most of the digestive tract, gallbladder, and excretory ducts of some glands.

Simple Columnar Epithelium

Description: Single layer of cubelike cells with large, spherical central nuclei. Function: Secretion and absorption. Location: Kidney tubules; ducts and secretory portions of small glands; ovary surface.

Simple Cuboidal Epithelium

Description: Single layer of thin, flattened cells Nuclei broad, thin. Function: Forms protective barriers Allows for diffusion and osmosis to occur. Location: Common at sites of diffusion in the body Lungs, capillaries, lining of body cavities. Can also form the a sack around other structures.

Simple Squamous Epithelium

Description: Long, cylindrical, multinucleate cells; obvious striations. Function: Voluntary movement; locomotion; manipulation of the environment; facial expression; voluntary control. Location: In skeletal muscles attached to bones or occasionally to skin.

Skeletal Muscle

Description: Spindle-shaped cells with central nuclei; no striations; cells arranged closely to form sheets. Function: Propels substances or objects: foodstuffs, urine, a baby, along internal passage- ways; involuntary control. Location: Mostly in the walls of hollow organs.

Smooth Muscle

Composed of multiple layers of cube-shaped cells. Protects areas such as the ducts of sweat glands, mammary glands, and salivary glands. Largest ducts of sweat glands, mammary glands, and salivary glands.

Stratified Cuboidal Epithelium

Composed of several cell layers; Surface cells are flattened; & keratinized. Basal cells are active in mitosis. Protects underlying tissues in areas subject to abrasion. Forms the epidermis of the skin, a dry membrane.

Stratified Keratinized Squamous Epithelium

Composed of several cell layers; Surface cells are flattened; Basal cells are active in mitosis. Protects underlying tissues in areas subject to abrasion. Forms the moist linings of the esophagus, mouth, and vagina.

Stratified Squamous Epithelium

A rare type of epithelial tissue composed of column shaped cells arranged in multiple layers. The cells function in secretion and protection. Found in the ocular conjunctiva of the eye, in parts of the pharynx and anus, the female's uterus, the male urethra and vas deferens.
