Anatomy
Mid-term review
| Term | Meaning |
|---|---|
| Anatomy | study of the structure and form of body parts |
| Physiology | study of body functions |
| Metabolism | all chemical changes within cells considered together |
| Homeostasis | state of balance in which the body's internal environment remains in the normal range |
| Levels of Organization | 7 levels: 1) Chemical 2)Organelle 3) Cellular 4) Tissue 5) Organ 6) System 7) Organism |
| Feedback Control Loops | controls homeostasis; controlled mainly by the nervous and endocrine systems |
| Negative Feedback Loop | opposite, inhibitory, opposes change by creating a response that is opposite in direction to the initial disturbance, most common in the body |
| Positive Feedback Loop | same, stimulatory, often dangerous, amplify/reinforce change |
| 3 basic components of a feedback control loop | 1) receptor 2) integrating/control center 3) effector mechanism |
| Afferent | signal traveling towards a particular center or point of reference |
| Efferent | moving away |
| Characteristics of Life (10) | 1)movement 2)growth 3) responsiveness (irritability) 4) reproductioin 5) respiration 6) digestion 7) absorbtion 8) circulation 9) assimilation 10) excretion |
| Body Regions | (blank) |
| Major Cavities | Dorsal, Ventral, and Abdominopelvic |
| Three Planes of the Body | 1) transverse ( t to b) 2) sagittal (s to s) 3) coronal (f to b) |
| Medial | closer to midline |
| Lateral | closer to the side of the body |
| Distal | further from the point of origin |
| proximal | closer to the point of origin |
| posterior | more toward the back of the body |
| anterior | more toward the front of the body |
| superior | above another body part |
| inferior | below another body part |
| deep | far from the surface |
| superficial | close to the surface |
| 4 types of tissues | connective, nervous, epithelial, and muscle |
| Tissue | group of cells with a similar structure and function |
| Epithelial Tissue | lack blood vessels, line/cover organs and systems |
| Functions of a tissue | connects, supports, transportation, and defends |
| Vascular | own blood supply |
| Avascular | no blood supply |
| Classification of epithelial tissue | membranous and glandular |
| Endocrine glad | secretes a hormone internally usually into the circulation |
| exocrine gland | secretes its products into ducts opening into an external or internal surface |
| Three types of exocrine glands | merocrine, holocrine, and apocrine |
| Fibroblast | epithelial: star shaped cells that produce fibers |
| mast cell | epithelial: produce heparine (blood thining substance) |
| macrophage | epithelial: engulf bacteria |
| adipocytes | stores energy in fat |
| bood cells | transports materials (red) fights invaders (white) |
| Types of fibers | Collagenous, Reticular, and Elastic |
| Functions of Skin | protection, regulation of body temp, communication, and synthesis/secretion |
| Layers of Skin | Epidermis, Dermis, Basement membrane, Subcutaneous layer, loose adipose tissue |
| Layers of the epidermis | corneum, lucideum, granulosum, spinosum, basal |
| Layers of the dermis | Papillary, reticular |
| 4 Types of Membranes | Serous, Cutaneous, Synovial, and Cutaneous |
| Skin proteins | Keratinocytes and Melanocytes |
| Integumentary system | skin, hair, nails and cutaneous glands |
| skin functions | protection, vitamen d production, sensation, and excretion |
