Tissues
Chapter 4 Anatomy and Physiology
| Question | Answer |
|---|---|
| A group of similar cells that perform the a common function is called | Tissues |
| the outermost layer of tissue is called the | Ectoderm |
| the middle layer of tissue is called the | Mesoderm |
| this inner layer of tissue is called the | Endoderm |
| Each layer gives rise to different types of tissues, this is a process called | Differentiation |
| Cells that can differentiate into many different types of cells, Such as liver cells, skin cells, or blood cells. | Stem Cells |
| this Layer, Gives rise to epidermis and nervous system | Ectoderm |
| This Layer, produces mucous membrane of the respiratory tract, thyroid gland, and secretory parts of the pancreas | Endoderm |
| This Layer, Gives rise to connective and ,muscle tissue | Mesoderm |
| Epithelial Tissue is also called | Epithelium |
| This tissue, is a continuous sheet of tightly packed cells | Epithelial Tissue |
| This tissue, covers the Body's surface | Epithelial Tissue |
| This tissue, Lines the body cavities and many of the organs | Epithelial Tissue |
| Cells that are "flat" and "Plate-like" are called | Squamous |
| Cells that are Cube-shaped are | Cuboidal |
| these cells are higher then they are wide, column-shaped cells are called | Columnar |
| If a Layer is "simple" it means | One Layer |
| If a Layer is "Stratified" it means | Many Layers |
| Modified cells containing secretory vesicles that produce large quantities of mucus | Goblet Cells |
| These Glands, secrete their products (such as tears, sweat, or gastric juices) into ducts | Exocrine |
| These Glands are offen called ductless | Endocrine |
| These glands secrete their products, Called hormones, directly into the blood | Endocrine |
| if a tissue consists of a single layer of flat, scale like cells its called | Simple Squamous Epithelium |
| this is tissue layer allows for ready diffusion or filtration because of its thinness | Simple Squamous Epithelium |
| If a tissue consists of a single layer of cube like cells its called | Simple Cuboidal Epithelium |
| this tissue layer secretes and absorbs | Simple Cuboidal Epithelium |
| If tissue layer consists of a single layer of columnar cells it is called | Simple Columnar Epithelium |
| This tissue layer secretes mucus by goblet cells | Simple Columnar Epithelium |
| if a tissue consists of a single layer of IRREGULARLY shaped columnar cells its called | Pseudostratified Columnar Epithelium |
| if a tissue layer consists of multiple layers or squamous cells its called | stratified Squamous Epithelium |
| the most widespread, and the most varied, of all tissues is called | Connective Tissue |
| What type of connective tissue is found in Ligaments? | Dense Fibrous |
| What type of connective tissue is found in fat? | Adipose |
| What type of connective tissue is found in Vertebral discs? | Cartilage |
| what type of connective tissue is found in the framework of the spleen? | Reticular |
| What type if connective tissue is found under epithelia? | Areolar |
| a key component of connective tissue that allows it to be so diverse is | Extracellular Matrix |
| these fibers are strong and flexible but not resist stretching | Collagenous |
| these fibers are the most abundant of fibers | Collagenous |
| these fibers occur in networks and support small structures such as capillaries and nerve fibers | Reticular |
| these fibers are made of protein called elastin | Elastic |
| these fibers can stretch and recoil like a rubber band | Elastic |
| this tissue consists of collagen and elastin fibers in a soft, gel-like matrix | Areolar Tissue |
| this tissue connects many adjacent structures in the body | Areolar Tissue |
| this tissue Surrounds blood vessels, nerves, the esophagus, and the trachea | Areolar Tissue |
| This tissue is Dominated by cells | Adipose Tissue |
| this tissue Forms supporting, protective pads around the kidneys and various other structures | Adipose Tissue |
| This tissue acts as a storage depot for excess food | Adipose Tissue |
| This tissue helps insulate the body to conserve body heat | Adipose Tissue |
| This tissue consists of a loose network of reticular fibers and cells | Reticular Tissue |
| this tissue forms the framework of the spleen, lymph nodes, and bone marrow | Reticular Tissue |
| Cord-like structures charged with attaching muscles to bones is called | Tendons |
| Attaching bone to bone is called | Ligaments |
| Dense connective tissue that forms bands or sheets that bind together organs and muscles are called | Fascia |
| the tissue that forms a protective capsule or sheath around the kidneys, spleen and nerves is called | Fascia |
| Cartilage is composed of cells called | Chondrocytes |
| This type of cartilage is found in the ends of movable joints, at the point where the ribs attach to the breast bone, and the supportive rings around the trachea | Hyaline Cartilage |
| This type of cartilage provides flexible support to the external ear and the epiglottis | Elastic Cartilage |
| This type of cartilage Forms the discs between the vertebrae and the knee joints | Fibrocartilage |
| Osseous tissue is another word for | Bone |
| Bone is composed of bone cells called | Osteocytes |
| A liquid matrix that surrounds blood cells is called | Plasma |
| The units that conduct nervous impulses are called | Neurons |
| These protect and assist neurons | Neuroglia |
| Each neuron has a large body, called a | Soma |
| Extending form the soma are multiple, short processes called | Dendrites |
| The neuron contains a single, long nerve fiber called the | Axon |
| Skeletal muscle consists of long, thin cells called | Muscle fibers |
| skeletal muscle may also be called | Striated or Voluntary muscle |
| These junctions allow electrical impulses to spread rapidly from cell to cell | Intercalated discs |
| this occurs when damaged tissue cells are replaced with the same type of cells, resulting in functional new tissue | Regeneration |
| this occurs when the damaged tissue is replaced with scar tissue, which is composed mainly of collagen | Fibrosis |
| Thin sheets of tissue that fulfill many crucial functions in the body is called | Membranes |
| Mucous membranes secrete | Mucus |
| A water solution that coast and protects the cells of the membrane | Mucus |
| this lines the spaces between bones, where they secrete synovial fluid to prevent friction during movement | Synovial Membranes |
