The brainstem is the part of the brain that connects the front part of the brain (cerebrum) to the spinal cord and the cerebellum. It is made of the midbrain, pons, and medulla. 1. What Does the Brainstem Do? The brainstem serves as a communication point between the body, the spinal cord, and the brain…
The brain receives blood from two pairs of arteries: the internal carotid arteries and the vertebral arteries which come together to form the circle of Willis at the base of the brain [1]. 1. Internal Carotid Arteries Internal carotid arteries consist of the left internal carotid artery and the right internal carotid artery which run…
The cerebellum is situated at the base of the brain in the posterior cranial fossa (the most posterior part of the skull base) and has the following functions: However, functional imaging studies indicated its potential involvement in cognition, including working memory, executive functioning (e.g., attention, reasoning, and problem-solving), time perception, language, and emotional processing [1]….
The sense of touch is controlled by the somatosensory cortex located in a region of the parietal lobe known as the post-central gyrus that is found on the middle top of the brain. In addition to its role in controlling touch, the somatosensory cortex is also involved in sensing temperature, pain, and body position and…
The part of the brain responsible for taste (gustation) is known as the gustatory cortex or primary gustatory cortex. It is involved in the perception and differentiation between different types of taste [1]. However, there are several steps before taste information reaches the gustatory cortex for processing: The papillae contain taste buds that are specialized…
