ANIMAL TISSUES Flashcards
(20 cards)
What results from the differentiation of several groups of cells that form a group of cells with the same function?
Tissues
What is the study of different tissues and how do tissues arise during embryonic development?
Histology.
What type of tissue is commonly found outside the body as coverings or linings of organs and cavities, and is characterized by closely-joined cells with tight junctions that serve as barriers for pathogens, mechanical injuries, and fluid loss?
Epithelial Tissue.
another term of epithelial tissues
polygonal cells
What type of epithelial cell is specialized for secretion?
Cuboidal.
What type of epithelial cell is brick-shaped and specialized for secretion and active absorption?
Simple columnar.
What type of epithelial cell has a plate-like shape and functions for the exchange of material through diffusion?
Simple squamous.
What type of epithelial cell consists of a single layer of cells that may appear stacked due to varying height, is found in the lining of the respiratory tract, and is usually lined with cilia to sweep mucus?
Pseudo-stratified columnar.
What type of epithelial cell is multilayered, regenerates quickly, and functions for protection?
Stratified squamous.
What type of tissues structurally differ according to their localization, and are important for support, protection, transport, insulation, repair, blood cell formation, and immunological responses?
Connective tissues.
What is made up of plasma (the liquid extracellular matrix), containing water, salts, and dissolved proteins, and includes erythrocytes that carry oxygen (RBCs), leukocytes for defense (WBCs), and platelets for blood clotting?
Blood.
What is made up of loose connective tissue found in the skin, fibrous connective tissue with collagenous fibers found in tendons and ligaments, and adipose tissue that stores fat to insulate the body and store energy?
CONNECTIVE TISSUE PROPER (CTP).
What is characterized by collagenous fibers embedded in chondroitin sulfate, contains chondrocytes that secrete collagen and chondroitin sulfate, and functions as a cushion between bones?
CARTILAGE.
What is mineralized connective tissue made by bone-forming cells called osteoblasts, which deposit collagen, and has a matrix of collagen combined with calcium, magnesium, and phosphate ions to make the bone hard, with blood vessels and nerves found in a central canal surrounded by concentric circles of osteons?
BONE.
What type of tissue is composed of long cells called muscle fibers that allow the body to move, either voluntarily or involuntarily, in response to signals from nerve cells?
Muscle Tissue.
What type of muscle tissue is striated and allows for voluntary movements?
Skeletal muscle.
What type of muscle tissue is striated, contains intercalated disks for synchronized heart contractions, and is involuntary?
Cardiac muscle.
What type of muscle tissue is not striated and is involuntary?
Smooth muscle.
What type of tissue is composed of nerve cells called neurons and glial cells, and functions to sense stimuli and transmit electrical signals throughout the body?
Nervous Tissue.
Give the three categorized muscle tissues
Skeletal, cardiac, smooth
