Anatomy Test #2
Tissue Test
| Question | Answer |
|---|---|
| Covers body surface and organs, cells of this tissue may absorb and/or secrete substances, lacks blood vessels, so nutrients diffuse through cells. | Epithelium |
| Allows for the movement of limbs and organs within the body, the major function of the cells of this tissue type is to shorten, attaches to bones, located in hollow organs. | Muscle |
| Transmits impulses for coordination, basis of the major controlling system of the body, forms the brain and spinal cord. | Nervous |
| Connects and supports body tissues, characterized by having large amounts of nonliving matrix, most widely distributed tissue type in the body | Connective |
| Lines respiratory passages and reprodutive tracts | Pseudostratified Columnar |
| Lines the ducts of mammary and sweat glands | Stratified Cuboidal |
| Forms the lining of the stomach and small intestine | Simple Columnar |
| Found in the lung sacs (alveolar tissue) | Simple Squamous |
| Forms the collecting tubules of the kidney | Simple Cuboidal |
| Found in the pharynx | Stratified Columnar |
| Forms the epidermis of the skin | Stratified Squamous |
| Found in the bladder lining | Transitional |
| Voluntarily controlled, banded appearance, multinucleate, found attatched to bones, allows you to direct your eyes, contains long, non-branching cylindrical cells, concerned with the locomotion of the body as a whole | Skeletal |
| Involuntarily controlled, single nucleus in each cell, contains cylindrical cells with branching ends, displays intercalated disks, tissue of the circulatory pump, banded appearance | Cardiac |
| Single nucleus in each cell, found in the walls of the stomach, uterus, and arteries, contains spindle shaped cells, changes the internal volume of an organ as it contracts, involuntarily controlled | Smooth |
| Very strong but lacks a good blood supply | Dense Connective |
| Forms the framework of lymph nodes | Reticular Connective |
| Found in intervertebral disks | Fibrocartilage |
| Provides strength and flexibility of the external ear | Elastic Cartilage |
| Bonds the skin to underlying organs | Loose Connective (areolar) |
| Provides insulation for the body | Adipose |
| Highly resistant to wear and found on the ends of articulating bones | Hyaline Cartilage |
| Contains cells arranged concentrically around a nutrient canal; matrix is hard due to mineral salts | Bone |
| Only tissue that has a liquid matrix | Blood |
| Allows for the flexibility of the spinal cord and some hollow organs | Elastic Connective |
| Site of ribosome formation | Nucleolus |
| Sacs within the cell that hold substances that recently entered the cell | Vesicles |
| Contain enzymes that digest worn cellular parts or substances that enter cells | Lysosomes |
| Provides for signal transduction and controls what enters and leaves the cell | Cell Membrane |
| Site of protein synthesis | Ribosomes |
| Modifies proteins for secretion and transport | Golgi Apparatus |
| Motile projections that help to propel fluids over the cellular surface | Cilia |
| Transform energy and release it from various molecules | Mitochondria |
| Sythensizes lipids and transports materials within a cell | Endoplasmic Reticulum |
| Motile projections that are capable of propelling a cell | Flagella |
| Contains the cellular information necessary to synthesize proteins | Chromatin |
| Contain enzymes that are important for the breakdown of organic molecules | Peroxisomes |
| What cell structure is the outermost limit of the cell and is extremely thin and selectively permeable? | Cell Membrane |
| The cell membrane is composed of a double layer of ________. | Phospholipids |
| What molecules are embedded in the membrane to strengthen? | Cholesterol Molecules |
| What molecule functions as enzymes and in signal transduction? | Peripheral Proteins |
| What molecule spans the membrane and aids in the passage of small molecules and ions? | Integral Proteins |
| What molecule functions as receptors for hormones and neurotransmitters? | Fibrous Proteins |
| Name the structure that prevents the separation of tissue layers and is found in tissues with great mechanical stress? | Desmosomes |
| What structure connects adjacent cells and allows for the passage of messages and molecules? | Gap Junctions |
| The type of transport that requires an input of energy is called _______ | active |
| The of transport that does not require an input of energy is called ______ | passive |
| Which transport uses membrane proteins that function as carriers to move molecules across the cell membrane? | facilitated diffusion/transport |
| Which transport is caused by the random motion of molecules? | diffusion |
| Which transport involves smaller molecules being forced through membranes from regions of higher pressure to regions of lower pressure? | filtration |
| Which transport requires energy to take a substance into the cell and the substance is progressively enclosed by a portion of the cell membrane? | endocytosis |
| Which transport requires energy to move molecules against a concentration gradient through carrier molecules in cell membranes? | active transport |
| Which transport requires energy to carry a substance rapidly from one side of the cell to the other? | transcytosis |
| Which transport requires energy to move a substance from the cell interior into the extracellular space? | exocytosis |
