Cells & Tissues
Tuesday Night
| Question | Answer |
|---|---|
| Cell | Simplest form oflife that can exist as a self-sustaining unit |
| Cell Membrane | Seperates the cytoplasm from the surrounding external environment |
| Cytoplasm | Gel-like intracelluar fluid within the cell membrane |
| Organelles | "Little organs" which are necessary for metabolism |
| Nucleus | Control center of the cell |
| Ribosome | Synthesizes proteins for use within a cell |
| Endoplasmic Reticulum (ER) | Synthesizes proteins and lipids |
| Mitochondria | The cell's "powerhouse/engery", because it's a site for cellular respiration |
| Lysosomes | Able to cause self-digestion of cell when the reduction of cells in an organism if needed |
| Golgi Apparatus | Referred to as the packing and shipping plant(warehouse) of the cell |
| True | Process of substance exchange across the cell's membrane is considered either an active or passive process? |
| False | Based on gradients of temperature, pressure, or concentration both active and passive processes require the expenditure of energy (ATP) |
| Diffusion | The movement of molecules, or other particules, from an area of high concentration to an area of low concentration? |
| Filtration | The movement of particlues across the cellular membrane due to Pressure |
| Osmosis | Movement of a pure solvent(water) from an area of Low concentration to an area of High conentration. |
| True | Osmosis, filtration, and diffusion are similar in that they require no cellular energy? |
| Phagocytosis | The process in which specialized cells ingest harmful microorganisms and cellular debris by "eating" them? |
| True | Pinocytosis is identical to Phagocytosis, except that pinocytic cells ingest liquids by "drinking" them? |
| Endocytosis | Moves large particles acorss the cell membrane into the cell |
| Epithelial Tissue | Functions in the process of absorption, excretion, secretion and protection |
| Connective Tissue | Represented by blood adn lymph |
| Muscle Tissue | Contracts and causes movement |
| Nervous Tissue | Acts as a channel for the transmission of messages |
| Connective | Binds structures together and serves as a framerwork |
| Epithelial | Froms the skin, the covering of the organs, and the inner lining of the hollow organs |
| Connective | Carries nutrients to teh cell and carries waste product away |
| Connective | Deep fascia, superficial fascia |
| Nervous | Initiates, controls, and coordinates the body's adaptation to its surroundings |
| Epithelial | Always has a free surface that is exposed to outside influences |
| Muscle | Responsible for the movement of food through the digestive tract, the constriction of blood vessels, and the emptying of the bladder |
| Connective | Bones, cartilage, ligament |
| Epithelial | Cells classifed by shape as squamous, cuboidal, and columnar |
| Connective | Collects into the lymphatic vessels along with metabolic waste and toxins |
| Epithelial | Covers all the surfaces of the body |
| Muscle | Responsible for pumping blood through the heart and into the blood vessels |
| Nervous | Composed of neurons |
| Connective | Circulates throughout the body |
| Muscle | Responsible for facial expressions, speaking and other voluntary movements |
| Muscous Membrane | Produces a thick, sticky substance that acts as a protectant and lubricant. They also line the body surfaces that open directly to the exterior |
| Serous Membrane | Produces a more watery, lubricating substance that lines the body cavities and sometimes forms the outermost surface of the organs containted in those cavities. Consists of two layers and partial lines the walls of the body cavities. |
| Serous Membrane | Visceral lining covers the organs found in the body cavities |
| Synovial Membrane | Lines the joint cavities of freely moving joints, and they secrete synovial fluid |
| Thixotrophy | The ability of fascia to change the ground substance in it's matrix from gel to a sol state and vice versa |
| Hyaline | The most common type of cartilage, covering the ends of bones |
| Elastic Cartilage | Found in the external ear and larynx |
| Areolar Tissue | Binds the skin to the underlying tissues and fills the space between muscles |
| Osseous Tissue | Impregnated with mineral salts, chiefly Calcium phosphate adn calcium carbonate |
| Adipose Tissue | Has an abundance of fat-containing cells |
| Ligaments | Fibrous bands that connect bone to bone |
| Fibrocartilage | Found between the vertebra adn in the pubic symphysis |
| Fibrous Connective Tissue | Composed of collagen adn elastin fibers which are closely arranged |
| Tendons | Cord or bands that serve to attach muscles to bones |
| Hyaline Cartilage | Found on the ends of bones and in movable joints |
