Superior rectus muscle elevates the eye

True

False

Expert Solution

Ans- True

There are six extra extraocular muscles which moves the eye ball. These are superior rectus, inferior rectus, superior oblique, inferior oblique, lateral rectus and medial rectus.

Upgaze, or turning the eye upward, is primarily the work of the superior rectus muscle, with some contribution by the inferior oblique muscle.Downgaze, or turning the eye downward, is primarily the work of the inferior rectus, with some contribution by the superior oblique.Abduction, or turning the eye outward toward the ear, is primarily done by the lateral rectus.Adduction, or turning the eye inward toward the nose, is primarily done by the medial rectus.The eye is rotated medially by the superior rectus and superior oblique, and is rotated laterally by the inferior rectus and inferior oblique. In addition, the levator palpebrae superioris muscle, which is not seen on the drawing, elevates the eyelid.

Serum glutamic oxaloacetic transaminase (SGOT) is an enzyme that elevates when the heart muscle is damaged. Assume that the population distribution of SGOT levels in adults with healthy hearts is known to be normally distributed with ? = 18.5 units/L and ? = 13.2 units/L. a. What proportion of adults with a healthy heart have an SGOT level of above 25 units/L? (0.5pts) b. For a sample size of ? = 40 from this population, what would be the sampling...

Smooth muscle contraction is regulated by the autonomic nervous system. During exercise, the sympathetic nerves that innervate the smooth muscles of bronchioles and arterioles regulate the contraction of these smooth muscles to increase ventilation and cardiac output. 2. Multiple choice: Choose one best statement. An infant born prematurely has neonatal respiratory...
