| Question | Answer |
|---|---|
| Which region is associated with the hip and is lateral to the hypogastric region? | iliac region |
| Which region is the umbilical region? | In the middle quadrant between the Left/Right Lumbar region |
| Which region is lateral to the umbilical region? | Lumbar region |
| Which region is associated with the lower ribs? | Hypochondriac region |
| The hypogastric region is where? | Inferior to the umbilical region |
| The epigastric region is where? | Superior to the umbilical region |
| The study of the FUNCTION of the body is called: | Physiology |
| Which type of tissue makes up skin, linings of internal pathways, and glands? | Epithelial tissue |
| The best description for the basic function of simple squamous epithelium is: | Absorption of gasses in lungs |
| What epithelial tissue is elastic and can be stretched? | Transitional |
| Superior | Toward the head |
| Inferior | Away from the head/towards the feet |
| Ventral/Anterior | In front of |
| Dorsal/Posterior | Behind |
| Proximal | Close to the origin of the body part or the point of attachment of a limb to the body trunk |
| Distal | Away from the origin of the body part or the point of attachment of a limb to the body trunk |
| Medial | Toward the midline |
| Lateral | Away from the midline |
| Superficial | Toward the body surface |
| Deep | Away from the body surface |
| Simple squamous | - single layer of flat cells Location: Usually form membranes, lines body cavities, lungs and capillaries - Functions in diffusion, filtration, or secretion |
| Simple cuboidal | - cube shaped, single layer (usually have open center for nucleus) Location: glands and ducts, forms wall of kidney tubules, covers ovaries - functions in secretion, filtration, and absorption - ciliated - propels mucus and reproductive cells |
| Simple columnar | - column like, single layer - includes mucus producing goblet cells Location: lines digestive tract - functions in secretion and absorption - ciliated - propels mucus and reproductive cells |
| Stratified squamous | - cells at apical surface are flattened - functions as a protective covering where friction is common Locations: lining if the skin, mouth and esophagus |
| Stratified cuboidal | - multiple layers of cuboidal cells - functions in protection - found mainly in large ducts of glands |
| Stratified columnar | - surface cells are columnar and cells under vary in size and shape - function in protection Location: larynx and male urethra, mainly in ducts of large glands |
| Pseudo-stratified | - columnar - single layer but some are shorter than others - often looks like a double layer of cells but rest on the basement membrane - functions in absorption and secretion Location: respiratory tract, ciliated |
| Transitional | - composed of modified stratified squamous epithelium - shape of cells depends on amount of stretching - functions in stretching and the ability to return to normal shape Location: lines organs of the urinary system |
| Glandular epithelium | One or more cells responsible for secreting a particular product |
| Exocrine (Secretions empty through ducts to the epithelial surface) Merocrine | - Releases substance through exocytosis (a vacuole that transports the substance to the cell surface) - no damage to the cell Ex: sweat glands |
| Exocrine: apocrine | - makes bud off of the cell membrane which break off into duct - cell loses part of its membrane Ex: mammary glands |
| Exocrine: holocrine | - cell bursts to release substances - cell destroyed in process Ex: Sebaceous glands |
| Endocrine (Ductless since secretions diffuse right into the blood vessels): Capillary | - lose their connection to the surface (duct) - all secretions are hormones - diffuse directly into the blood vessels that weave through glands Ex: thyroid, adrenal, and pituitary glands |
| Connective tissue | - found everywhere in the body - includes most abundant and widely distributed tissues Functions: Binds body tissues together, supports the body, and provides protection |
| Extracellular Matrix | Non-living material that surrounds living cells |
| Osteocytes: Bone Osseous tissue | - Bone cells in lacunae (cavities) - hard matrix of calcium salts - large numbers of collagen fibers - functions to protect and support the body |
| Fibrocytes: Connective Tissue Proper Areolar | - most widely distributed connective tissue - soft, pliable tissue like "cobwebs" - Functions like packing tissue - contains all fiber types - can soak up excess fluid |
| Dense connective tissue | Tendons: "regular" strength in one direction. Attack skeletal muscle to bone. Dermis: "irregular" strength in all directions. Lower layers of skin. Ligaments: "elastic" strength in many directions that is flexible and provides cushion. Attach bone to b |
| Chondrocytes: Cartilage Hyaline Cartilage | - Most common type of cartilage Made of: Abundant collagen fibers, rubbery matrix Locations: larynx, entire fetal skeleton prior to birth - functions as more flexible skeletal element than bone |
| Fibrocartilage | -Highly compressible Location: Forms cushion like discs, between vertebrae |
| Elastic Cartilage | - Provides elasticity Location: Supports the external ear |
| Blood Cells: | - Functions as a transport vehicle for materials Vascular: surrounded by fluid matrix called blood plasma , fibers are visible during clotting |
| Mast Cells | - Detect foreign substances, contain granules that secrete inflammatory chemicals. |
| Macrophage | - Blob-like cells that engulf invaders |
| Red Blood Cells | Provide oxygen to cells are donut shaped |
| Muscle Tissue | Function to produce movement |
| Smooth | - Under involuntary muscle - Found in walls of hollow organs such as stomach, uterus, blood vessels Characteristic: no visible striations, one nucleus per cells, Spindle- shaped cells |
| Cardiac | - Under involuntary control - Found only in the heart - Function is to pump blood Characteristics: Striated, only one nucleus per cells, cells are attached to other cardiac muscle cells at intercalated disks |
| Skeletal | - under voluntary control - Contracts to pull bones or skin - Produces gross body movements or facial expressions Characteristics: striated, Multinucleate (more than one nucleus), long cylindrical cells |
| Nervous Tissues: | Composed of neurons and nerve support cells - Function is to send impulses to other areas of the body |
| Neurons | -Make up only 10% of tissue - Convert stimuli to nerve -Pass impulses to other neurons, glands, and muscle fibers - Neurons don't regenerate (most of the time) |
| Neuroglia | - make up 90% of the nervous tissue -protect and support neurons - can regenerate after injury |
