---|---|
Associated with various organs | Peri |
Next to the heart | Pericardium |
Next to the bone | Periosteum |
Next to the cartilage | Perichondrium |
Covers, separates and protects skeletal muscle | Deep Fascia |
Insulates the body and protects the skin, located beneath the skin | Superficial Fascia |
Dense, regular, connective tissue- bands that wrap around muscle | Fascia |
Covers parts of nervous tissue | Meninges |
Lines the joint cavities and small cushions near the joints (bursae) | Synovial membranes |
Skin | Cutaneous |
Lines tubes and other spaces that open to the outside of the body | Mucous |
Lines the walls of the abdominal cavity, covers the organs; supports and protects the structures within the abdomen. | Peritoneum |
Sac that holds the heart divided into | Serous pericardium |
Area holding the lungs | Pleurae |
On the surface of the organs, intimate covering of the lungs | Visceral membranes |
Attached to the body wall, lines thoracic cavity | Parietal membranes |
Lines the body cavities | Serous membranes |
Surface is made of epithelium | Epithelium Membranes |
A thin sheet or layer of pliable tissue, serving as a covering or envelope of a part, as the lining of a cavity, as a partition or septum, or as a connection between 2 structures | Membranes |
No epithelium tissue | Connective Tissue Membranes |
Four types of tissues | Epithelial, Connective, Muscular and Nervous |
Is avascular and innovated. Covers surfaces, lines cavities and forms glands | Epithelial Tissue |
Is vascular, has extra cellular matrix which includes adhesion proteins and polysaccharides. Supports and frames the framework of the body. | Connective Tissue |
Controls and allows movement | Muscular Tissue |
Transmits impulses, only tissue in body that will not regenerate. | Nervous Tissue |
Single cell layered, Absorption and excretion of products and waste | Simple Epithelial Tissue |
Nuclei not in a certain position. Found in respiratory tract, cilia along the top of the cell | Psuedostratified Epithelial Tissue |
Multiple layers of cells in order to provide protection. Allows for wear and tear. On soles of hands and feet. | Stratified Epithelial Tissue |
Allows for expansion and contraction. Found in urinary tract, the bladder and ureters. | Transitional Epithelial Tissue |
Flat and irregular tissue | Squamous Epithelial Tissue |
One layer thickness. Allows passages of nutrients, gases and wastes in the lungs. | Simple Squamous Epithelial Tissue |
Covers the heart, preventing the heart from eroding due to constant blood flow. Found in lymphatic and blood vessels. | Endothelium |
Lines the ventricle cavity organs- abdominopelvic and thoracic. Protects the organs from friction, where the organs rub against each other. | Mesothelium |
Cubed shaped, 3-dimensional cells. Forms lining of several glands and ducts including kidneys. | Cuboidal |
Long, narrow columns with 3-dimensional shape. Nuclei loacted towards the bottom and cytoplasm towards the top. Found towards digestive tract. | Columnar |
Groups of epithelial cells that make and secrete a product | Glands |
Are internal glands, secretes products into the bloodstream. Ex: hormones | Endocrine Glands |
External glands, secrete products to exit the cell or body OR go into the lumen of another organ. Ex: sebaceous, salivary and mammary glands | Exocrine Glands |
Inside space. Ex: ear canal, nasal cavity | Lumen |
Only organ that has both endocrine and exocrine glands | Pancreas |
Found with columnar tissue. Helps with mucous production. | Goblet cells |
Is a straight tube that opens directly to the surface. Found in intestinal tract. | Simple Tubular Glands |
Branched tubelike gland, with a short duct or no duct. Found in gastric region. | Simple Branched Tubular Glands |
Long coiled tubelike gland with a long duct, J-shaped. Found in sweat glands. | Simple Coiled Tubular Glands |
Shaped like a 3-leaf clover, secretes sebum (oil). Found in sebaceous glands. | Simple Branched Alveolar Glands |
Looks like a leaf. Found in the Bulbourethral glands of males. Is a complex gland. | Compound Tubular Glands |
Irregularly branched tubules with numerous saclike outgrowths. Found in mammary glands | Compound Alveolar Glands |
Gland that secretes sweat and odor | Psudoriferous |
Secrete products through the cell. Ex: Salivary glands, pancreatic glands and sweat glands of the skin | Merocrine Glands |
Secretes products and the top part of the cell, the apex. Ex: Mammary glands and ceruminous glands in ear canal | Apocrine Glands |
Earwax | Ceruminous |
Secretes the cell and its product. Ex: Sebaceous glands of the skin | Holocrine Glands |
Secretes fibers into extracelluar connective tissue. Provides support. | Fibroblast |
Big eaters, Phagotizes anything not appropriate for the body. Ex: hungry teenage boys. | Macrophage |
Located near blood cells. Releases heparin and histamine for allergies. | Mast cells |
Blood and Lymph connects the tissues together | Liquid or Vascular Connective Tissue |
Types of Soft or Loose Tissue | Adipose, Areolar and Reticular tissues |
Fatty tissue | Adipose Tissue |
All other tissues or cells are bordered by it or embedded in it. | Areolar Tissue |
A delicate of interwoven fibers, that function as a stroma (net) to support free blood cells. Ex: Lymphatic tissue or bone marrow. | Reticular Tissue |
Net | Stroma |
Contains collagen. Forms ligaments, tendons and capsules (shells) of certain organs. Found in the kidneys. | Fibrous or Dense Tissue |
Flexible white protein | Collagen |
Cartilage and Bone | Hard Connective Tissue |
No fibers. Hard, protective covering over long bones. Can erode away. | Hyaline Cartilage |
Visible fibers around the matrix of cells. Little flexibility. In between vertebral discs and the 2 pubic bones. | Fibrocartilage |
Fibers in many directions. Allows flexibility or movement. Provides framework in ears and parts of the larynx. | Elastic Cartilage |
Osseous Tissue | Bone |
Bone building cells | Osteoblasts |
Breaking down bone cells | Oseoclasts |
Bone maintenance cells | Osteocytes |
Types of cartilage tissues | Hyaline, Fibrocartilage and Elastic Cartilage Tissues |
Types of muscle tissues | Cardiac, Skeletal and Smooth Muscle tissues |
Types of Nervous tissues | Neurons and Neuroglia Tissues |
Associated with skeleton. Voluntary muscle control. Striated muscle fibers of actin and myotin | Skeletal Tissue |
Heart muscle tissue. Is striated and has intercolated disks to reinforce the muscle tissue. Involuntary control. | Cardiac Tissue |
No striations. Involuntary control. Located primarily in digestive system. Found in walls of hollow organs. | Smooth Muscle Tissue |
Are impulse transmitting cells that make up nervous tissue | Neurons |
Brings impulses into the cell. | Dendrites |
Body of the cell | Somite or Pericarron |
Transmits information away from the cell | Axon |
These cells do not transmit impulses. They nourish, protect and clean up after the neurons. The "mom cells" | Neuroglia cells |
Tissue mass that is formed when cells lose division control | Tumor |
Remains in place like a lump, eventually interferring with the function of healthy tissue | Benign Tumor |
Is invasive, extending into surrounding tissue. May resemble a crab with outreaching claws | Malignant Tumor |
