Anatomy and physiology final exam study guide questions with complete answers

Anatomy and physiology final exam study guide questions with complete answers Homeostasis - Answer-all body systems working together to maintain a stable internal environment Positive Feedback - Answer-the response of the effector increases change of the stimulus. The body is moved away from homeostasis (normal range is lost) and this type of feedback is used to speed up processes. Negative Feedback - Answer-the response of the effector negates (rules out) the stimulus and body is brought back into homeostasis (normal range is achieved). Anatomical Directions - Answer-Anterior- front Ventral- belly side Posterior/Dorsal- the backside Cranial/Cephalic- head Superior- Above Caudal- tail Interior- below Medial- Towards the midline (belly botton) Lateral- away from the midline (moving laterally from your nose you end up at your cheeks) Proximal- toward attached base (the thigh is proximal to the foot) Distal- away from attached base (fingers are distal to the wrist) Superficial- toward or on the bodys surface Deep- Farther from the bodys surface (bone is deep to the surrounding skeletal muscles) Sectional Planes - Answer-Transverse- separates superior from inferior portionscross section (top and bottom) horizontal Frontal- separates anterior from posterior (front and back) Sagittal- separates right and left portions (down the middle) Midsagittal- plan passes through the mid line
