Answer the following question given this paragraph: When most people think of muscles, they think of the muscles that are visible just under the skin, particularly of the limbs. These are skeletal muscles, so-named because most of them move the skeleton. But there are two other types of muscle in the body, with distinctly different jobs. Cardiac muscle, found in the heart, is concerned with pumping blood through the circulatory system. Smooth muscle is concerned with various involuntary movements, such as having one's hair stand on end when cold or frightened, or moving food through the digestive system. This chapter will examine the structure and function of these three types of muscles. Q: What kind of muscle is found in the heart? Choices: - cord - respiratory - pulminary - cardiac A:
cardiac
Answer the following question given this paragraph: Nerves of the Face and Oral Cavity An iconic part of a doctor's visit is the inspection of the oral cavity and pharynx, suggested by the directive to "open your mouth and say 'ah. '" This is followed by inspection, with the aid of a tongue depressor, of the back of the mouth, or the opening of the oral cavity into the pharynx known as the fauces. Whereas this portion of a medical exam inspects for signs of infection, such as in tonsillitis, it is also the means to test the functions of the cranial nerves that are associated with the oral cavity. The facial and glossopharyngeal nerves convey gustatory stimulation to the brain. Testing this is as simple as introducing salty, sour, bitter, or sweet stimuli to either side of the tongue. The patient should respond to the taste stimulus before retracting the tongue into the mouth. Stimuli applied to specific locations on the tongue will dissolve into the saliva and may stimulate taste buds connected to either the left or right of the nerves, masking any lateral deficits. Along with taste, the glossopharyngeal nerve relays general sensations from the pharyngeal walls. These sensations, along with certain taste stimuli, can stimulate the gag reflex. If the examiner moves the tongue depressor to contact the lateral wall of the fauces, this should elicit the gag reflex. Stimulation of either side of the fauces should elicit an equivalent response. The motor response, through contraction of the muscles of the pharynx, is mediated through the vagus nerve. Normally, the vagus nerve is considered autonomic in nature. The vagus nerve directly stimulates the contraction of skeletal muscles in the pharynx and larynx to contribute to the swallowing and speech functions. Further testing of vagus motor function has the patient repeating consonant sounds that require movement of the muscles around the fauces. The patient is asked to say "lah-kah-. Q: Which nerve directly stimulates the contraction of skeletal muscles in the pharynx and larynx to contribute to the swallowing and speech functions? Choices: - glands nerve - larynx nerve - gland nerve - vagus nerve A:
vagus nerve
Q: Answer the following question given this paragraph: Characteristics of Blood When you think about blood, the first characteristic that probably comes to mind is its color. Blood that has just taken up oxygen in the lungs is bright red, and blood that has released oxygen in the tissues is a more dusky red. This is because hemoglobin is a pigment that changes color, depending upon the degree of oxygen saturation. Blood is viscous and somewhat sticky to the touch. It has a viscosity approximately five times greater than water. Viscosity is a measure of a fluid's thickness or resistance to flow, and is influenced by the presence of the plasma proteins and formed elements within the blood. The viscosity of blood has a dramatic impact on blood pressure and flow. Consider the difference in flow between water and honey. The more viscous honey would demonstrate a greater resistance to flow than the less viscous water. The same principle applies to blood. The normal temperature of blood is slightly higher than normal body temperatureabout 38 C (or 100.4 F), compared to 37 C (or 98.6 F) for an internal body temperature reading, although daily variations of 0.5 C are normal. Although. Q: What is the term for the measure of a fluid's thickness? Choices: - friction - elasticity - salinity - viscosity A:
A: viscosity
Question: Answer the following question given this paragraph: Animal behavior is any way that animals act, either alone or with other animals. Q: What do we call any way that animals act, either alone or with other animals. Choices: - typical behavior - animal habits - animal communication - animal behavior A:
Answer: animal behavior
*Question*
Answer the following question given this paragraph: Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities. Q: Objects moving at different speeds, in different directions have different what? Choices: - protons - vibrations - electrons - velocities A:

Q: Answer the following question given this paragraph: Epithelial tissue from epithelium. Below this is dermis, thicker and with blood vessels. Two specialized epithelia: pseudostratified transitional Pseudostratified epithelia lines the trachea (where it is ciliated)and the male urethra (where it is non ciliated), looks stratified but not. Transitional epithelia found only in bladder and urinary system. As it stretches it appears to go from 6 to 3 cell layers deep. Glandular epithelia (gland: group of cells that excretes something. mostly derived from epithelium. Glands are classified into endocrine and exocrine by where they excrete. Endocrine glands secrete hormones into the blood without use of ducts. Exocrine glands secrete onto the body surface or into a cavity, thru a duct. Exocrine substances include sweat, mucous, oil, and saliva. An exocrine gland is the liver, which secretes bile. Q: Is sweat an exocrine or endocrine substance? Choices: - neither - both - exocrine - exocrine A:
A: exocrine
