a. pollex b. tarsal c. hallux d. pedal e. carpal -CORRECT ANSWERS-c. hallux cardiomyopathy worsens as the heart weakens. swelling in the legs occurs & is classified as a (select all that apply): a. symptom b. disorder c. disturbance d. disease e. sign -CORRECT ANSWERS-b. disorder & c. disturbance & e. sign choose the directional term that would make the following sentence correct. the heart is ___________ to the liver a. inferior b. anterior c. contralateral d. superior e. superficial -CORRECT ANSWERS-d. superior choose the directional term that would make the following sentence correct. the sternum is ___________ to the heart a. posterior b. anterior c. inferior d. superior e. lateral -CORRECT ANSWERS-b. anterior cutting open the chest at the sternal marking would represent a(n) a. sagittal plane b. midsagittal plane c. transverse plane d. oblique plane e. coronal plane -CORRECT ANSWERS-b. midsagittal plane cutting the body in half at the diaphragm, would create the thoracic cavity & the abdominopelvic cavity. what plane would create these halves? a. frontal b. sagittal c. transverse d. oblique e. midsagittal -CORRECT ANSWERS-c. transverse describe a feedback system & list its general components -CORRECT ANSWERS-a feedback loop is a cycle of events in which the status of the body condition is monitored, evaluated & changed to maintain homeostasis. a feedback system will include a receptor that detects the stimuli, a control center that receives the input from the receptor & generates an output, & an effector that receives the output & produces a response. describe the anatomical position -CORRECT ANSWERS-in the anatomical position, the subject stands erect facing the observer w/ the head level & the eyes facing forward. the feet are flat on the floor & directed forward & the arms are at the sides w/ the palms turned forward describe the differences between positive & negative feedback systems -CORRECT ANSWERS-a positive feedback system will strengthen or reinforce a change in one of the bodies controlled conditions while a negative feedback system will reverse a change in a controlled condition discuss the importance of body fluids & which one is considered to be the body's internal environment - CORRECT ANSWERS-an important aspect of homeostasis is maintaining the volume & composition of body fluids, which are dilute, watery solutions containing the dissolved substances needed to sustain life. the fluid w/in cells is intracellular fluid (ICF) & the fluid found outside of cells is extracellular fluid (ECF). the ECF consists of interstitial fluid, blood plasma, lymph, cerebrospinal fluid, synovial fluid, aqueous humor, & vitreous. the ECF called interstitial fluid, which is the fluid found in the narrow spaces between cells & tissues, is also known as the body's internal environment. this is due to the fact that the proper functioning of body cells depends on precise regulation of the composition of the interstitial fluid surrounding them. during a cadaver lab, the professor requests the students to cut the head w/ a transverse plane/a coronal plane. describe the results a. the student will have two halves, right & left b. the student will have two halves, superior & inferior c. the student will have two halves, anterior & posterior d. student will have four parts; divided vertically into anterior & posterior, & superior & inferior e. the student will have four parts; divided into right & left, & anterior and posterior -CORRECT ANSWERS-d. student will have four parts; divided vertically into anterior & posterior, & superior & inferior during a visit to your doctor, you complain about headache & anxiety. these changes in your body functions are considered a. signs b. symptoms c. receptors d. controlled condition e. responsiveness -CORRECT ANSWERS-b. symptoms during sexual intercourse, stimulation leads to an increase in arousal & sexual behavior. this in turn leads to increased stimulation, until climax is reached & orgasm takes place. this is an example of a. positive feedback b. negative feedback -CORRECT ANSWERS-a. positive feedback explain the relationship between the skeletal system & the urinary system? -CORRECT ANSWERS-the skeletal system supports & protects organs w/in the body, stores minerals. w/in the bones are the cells that produce blood cells. the urinary system helps regulate the production of red blood cells & helps maintain the body's mineral balance.
