BIOL 252 Anatomy 2 Review Exam With Actual Question and Rationale Answer

BIOL 252 Anatomy 2 Review Exam With Actual Question and Rationale Answer cerebellum - ANSWER It consists of two highly convoluted lobes connected by a piece called the vermis (VER-miss). Like the cerebral hemispheres, the outer portion of the cerebellum, known as the cerebellar cortex, is gray matter, while the inner region is white matter. The cerebellar white matter is called the arbor vitae (AHR-bohr VEE-tay) because of its resemblance to the branches of a tree. The cerebellum coordinates and plans ongoing motor activities and is critical in reducing and preventing motor error with movement. brainstem, - ANSWER influences the automatic functions of the body midbrain (brainstem) - ANSWER The most superior portion of the brainstem is the midbrain, which has roles in movement, sensation, and certain reflexes superior and inferior colliculi - ANSWER Posterior to the midbrain are two projections called the superior and inferior colliculi (koll-IK-yoo-lye), which relay visual and auditory stimuli to the thalamus, respectively. pons (midbrain) - ANSWER Inferior to the midbrain we find the rounded pons, which bulges anteriorly. Nuclei 13 of the pons are involved in controlling the rhythm for breathing and the sleep cycle medulla oblongata (midbrain) - ANSWER The last segment of the brainstem, the medulla oblongata (or simply medulla), is continuous inferiorly with the spinal cord. The nuclei in the medulla work with those of the pons to control ventilation and are also involved in regulating heart rate, blood pressure, and certain reflexes such as vomiting. meninges - ANSWER that a set of three membranes, collectively called the meninges (meh-NIN-jeez; singular: meninx), surrounds the brain. The meninges include the following: Dura mater Arachnoid mater. Pia mater.
