| Question | Answer |
|---|---|
| Simple Cuboidal function | Secretion and Absorption |
| Simple Cuboidal Location | Kidneys |
| Transitional Function | Provides Stretch |
| Transitional Location | Bladder, ureters, urethra |
| Simple Squamous Function | Filtration (kidneys), diffusion (air sacs of the lungs) |
| Simple Squamous Location | Alveoli of lungs, kidney glomeruli, lining of vessels |
| Simple Columnar Location | Intestinal tract |
| Simple Columnar Function | Absorption, secretion of mucus, enzymes, and other substances |
| Pseudostratified Ciliated Columnar Location | Trachea and bronchial tubes |
| Pseudostratified Ciliated Columnar Function | Secretion of mucus, propulsion of mucus by cilia |
| Stratified Squamous Location | Lines mouth,vagina, esophagus, skin |
| Stratified Squamous Function | Protection |
| Specific types of stratified squamous | Keratinized Non-keratinized |
| Major types of adult tissues | Epithelial Connective Muscle Nervous |
| Main classes of connective tissue | Connective tissue proper (Fibrous Tissue) Cartilage Bone tissue Blood |
| Functions of connective tissue | Enclose organs-Areolar Connect tissues to one another-Tendons and ligaments (Dense connective tissue) Support and movement-Bone Storage-Fat Insulation-Fat Transport-Blood Protection-Bones, cells of the immune system |
| Fibroblasts | secrete the protein needed for fiber synthesis and components of the extracellular matris |
| Adipose (adipocytes) | Common in some tissues (dermis of skin); rare in some cartilage |
| Mast Cells | Common beneath membranes; along small blood vessels. can release heparin, histamine, and proteolytic enzymes in response to injury |
| Leukocytes | Respond to injury or infection |
| Macrophages | Derived from monocytes (a WBC). Phagocytic; provide protection |
| Chondroblasts | Form cartilage |
| hematopoietic stem cells | form blood cells |
| undifferentiated mesenchyme (stem cells) | have potential to differentiate into adult cell types |
| The 3 major components of ECM | 1.Protein fibers(Collagen, Elastic, Reticular) 2.Ground substance 3.Fluid |
| Collagen Fibers | Composed of the protein collagen. strong, flexible, inelastic; great tensile strength. Perfect for tendons, ligaments |
| Elastic Fibers | Contain molecules of protein elastin that resemble coiled springs. Returns to its original shape after stretching or compression. Perfect for lungs, large blood vessels |
| Reticular Fibers | Formed from fine collagenous fibers; form branching networks (stroma). fill spaces between tissues and organs. |
| Adipose Tissue Function | Protection, storage |
| Adipose tissue Location | Under the skin, around the eyes kidneys, heart |
| Reticular (Loose) Connective Tissue Location | Internal skeleton: lymph nodes, spleen |
| Reticular (Loose) Connective Tissue Function | Soft internal skeleton, supports other cell types. |
| Hyaline Function | support, reinforce, resist compressive stress |
| Hyaline Location | Embryonic skeleton, cover end of bones, trachea, nose, larynx |
| Aerolar Loose Connective Function | Wraps and cushions organs; inflammation |
| Aerolar Loose Connective Loction | Widely distributed under epithelia |
| Dense connective Tissue Location | Tendons, ligaments, aponeurosis |
| Dense connective Tissue Function | Attaches muscles to bones and bones to bones |
| Osseous Tissue Function | Storage, support |
| Osseous Tissue (Compact) Location | Bones |
| Spongy Bone or Cancellous Bone function | Support |
| Spongy Bone or Cancellous Bone Location | In the center of flat bones and in the ends of long bones |
| Types of blood cells | Erythrocytes-RBC Leukocytes-WBC Thrombocytes-Platlettes |
| Characteristics of muscle tissue | -cells are referred to as fibers -contracts or shortens w/force when stimulated -moves entire body and pumps blood |
| Types of Muscle tissue | Skeletal-attaches to bones Cardiac-muscle of the heart Smooth-muscle associated w/tubular structures and with the skin. nonstriated and involuntary |
| Skeletal Muscles Function | Voluntary movement locomotion manipulation of the environment facial expression voluntary control |
| Skeletal Muscles Location | muscles attached to bones or occasionally to skin |
| Cardiac Muscles Location | The walls of the heart |
| Cardiac Muscles Funtion | As it contracts, it propels blood into the circulation involuntary control |
| Smooth Muscle Function | Propels substances or objects along internal passageways (foodstuff, urine, baby) |
| Smooth Muscle Location | Mostly in the walls of hollow organs |
| Nervous Tissue function | transmit electrical signals from sensory receptor and to effectors (muscles and glands) that control their activity |
| Nervous Tissue Location | Brain, spinal cord, and nerves |
| Layers of the Epidermis | Stratum Corneum Stratum Lucidum Stratum Granulosum Stratum Spinosum Stratum Basale |
