Answer the following question given this paragraph: Movement at Synovial Joints The wide range of movement allowed by synovial joints produces different types of movements. The movement of synovial joints can be classified as one of four different types: gliding, angular, rotational, or special movement. Gliding Movement Gliding movements occur as relatively flat bone surfaces move past each other. Gliding movements produce very little rotation or angular movement of the bones. The joints of the carpal and tarsal bones are examples of joints that produce gliding movements. Angular Movement Angular movements are produced when the angle between the bones of a joint changes. There are several different types of angular movements, including flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. Extension is the opposite of flexion in that the angle between the bones of a joint increases. Straightening a limb after flexion is an example of extension. Extension past the regular anatomical position is referred to as hyperextension. This includes moving the neck back to look upward, or bending the wrist so that the hand moves away from the forearm. Abduction occurs when a bone moves away from the midline of the body. Examples of abduction are moving the arms or legs laterally to lift them straight out to the side. Adduction is the movement of a bone toward the midline of the body. Movement of the limbs inward after abduction is an example of adduction. Circumduction is the movement of a limb in a circular motion, as in moving the arm in a circular motion. Q: What kind of joints are capable of a wide range of movements, classified as gliding, angular, rotational, or special? Choices: - glandular - locking - fibrous - synovial A:
(Answer)
synovial
Ques: Answer the following question given this paragraph: When ordered by atomic number, the discrepancies within Mendeleev's table disappeared. Tellurium has an atomic number of 52, while iodine has an atomic number of 53. Even though tellurium does indeed have a greater average atomic mass than iodine, it is properly placed before iodine in the periodic table. Mendeleev and Moseley are credited with formulating the modern periodic law , which states that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties. We will discuss some of these chemical and physical properties later on in this chapter. The result is the periodic table as we know it today. Q: Even though tellurium does indeed have a greater average atomic mass than iodine, it is properly placed before iodine in the? Choices: - theory table - phases table - cycles table - periodic table A:
Ans: periodic table

Answer the following question given this paragraph: A: Earth has north and south magnetic poles. The North Pole is located at about 80 degrees north latitude. The magnetic field is an area around Earth that is affected by its magnetic field. The field is strongest at the poles, and lines of magnetic force move from the north to the south magnetic pole. Q: What is located at about 80 degrees north latitude? Choices: - alaska - india - the equator - the north pole A:
(A).
the north pole
Ques:Answer the following question given this paragraph: The Hypothalamus The hypothalamus is the control center for many homeostatic mechanisms. It regulates both autonomic function and endocrine function. The roles it plays in the pupillary reflexes demonstrates the importance of this control center. The optic nerve projects primarily to the thalamus, which is the necessary relay to the occipital cortex for conscious visual perception. Another projection of the optic nerve, however, goes to the hypothalamus. The hypothalamus then uses this visual system input to drive the pupillary reflexes. If the retina is activated by high levels of light, the hypothalamus stimulates the parasympathetic response. If the optic nerve message shows that low levels of light are falling on the retina, the hypothalamus activates the sympathetic response. Output from the hypothalamus follows two main tracts, the dorsal longitudinal fasciculus and the medial forebrain bundle (Figure 15.11). Along these two tracts, the hypothalamus can influence the EddingerWestphal nucleus of the oculomotor complex or the lateral horns of the thoracic spinal cord. Q: What is considered to be the control center for homeostatic mechanisms? Choices: - thyroid - hippocampus - adrenal cortex - hypothalamus A:

Ans:hypothalamus
