largest bart of the brain. it consists of two hemispheres separated by a deep longitudinal fissure. it is the seat of consciousness and the center of the higher mental functions such as memory, learning, reasoning, judgement, intelligence, and emotions.
portion of the brain located dorsally to the pons and medulla oblongata. it plays an important role in the fine control of voluntary muscular movements.
the part of the brain connecting the cerebral hemisphere with the spinal cord. it is comprised of the medulla oblongata, the pons, and the midbrain.
portion of the brain important for controlling certain metabolic activities, including the regulation of body temperature
reticular activating system (RAS)
a series of nervous tissues keeping the human system in a state of consciousness.
process of tissue responsible for the communication interchange between the cerebellum, the cerebrum, midbrain, and the spinal cord.
lower portion of the brainstem containing the respiratory, cardiac, and vasomotor centers.

a network of vessels that drains fluid, called lymph, from the body tissue. Lymph nodes help filter impurities en route to the subclavian vein and then to the heart.

what are the 5 sections of the spine?
cervical spine C1-7; thoracic spine T1-12; Lumbar L1-5; sacral S1-5; coccygeal spine about 4 fused vertebrae
central medial region of the lung where the bronchi and pulmonary vasculature enter the lung.
the large arteries and veins located in the mediastinum that enter and exit the heart; the aorta, superior/inferior vena cava, pulmonary arteries, and pulmonary veins.
