The brain anatomy is undoubtedly difficult, with a plethora of anatomical words to memorize. Fortunately, assistance is available. Continue reading to get our best recommendations for handling this perplexing subject.
The cerebrum, which is composed entirely of grey matter, is the brain's biggest and most developed region. It consists of motor regions that regulate voluntary movement, sensory areas that process information from sensory receptors located throughout the body, and association areas that link the motor and sensory areas. The cerebrum's structure:
The cerebrum is the brain's biggest and most complicated region. The cerebrum's job is to regulate our conscious and unconscious behaviors and ideas, as well as our reactions to stimuli. The cerebrum is often split into four distinct lobes: temporal, parietal, occipital, and frontal. The cerebrum's temporal lobe is responsible for auditory perception, as well as memory and speaking processes. The hippocampus is positioned inside the temporal lobe and is responsible for memory formation. Additionally, the hippocampus is involved in the linkage of memories and emotions, as well as the capacity to acquire relationships between ideas. If this part of the brain is injured, difficulties with language and memory development will show. Additionally, the pituitary gland is located in the temporal lobe and is connected to the brain by a structure called the pituitary stalk. The pituitary gland's job is to regulate hormone levels in the body, especially those that govern and stimulate sexual development, regulate stress reactions, promote bone and muscle growth, and combat illness. The pituitary gland does this by exerting control over other glands in the body known as endocrine glands.
The study of "split-brain patients"âpeople who had surgical transection of the corpus callosum in an effort to minimize the severity of epileptic seizuresâhas contributed significantly to our present knowledge of the interactions between the two hemispheres.
[113] These individuals do not exhibit immediately noticeable abnormal behavior, but in some circumstances behave almost as if they are two separate persons in the same body, with the right hand doing an action and the left hand reversing it. [113] [114] When these patients are briefly shown a picture on the right side of their visual fixation point, they are able to describe it verbally; however, when the picture is shown on the left, they are unable to describe it verbally, but may be able to indicate the nature of the object shown with their left hand.

The thalamus, the diencephalon's biggest structure, acts as a relay station for all sensory information that enters the cortex and is finally sent to the cerebrum for processing. Although the hypothalamus receives sensory input as well, all of the information processed by the hypothalamus originates from the autonomic nervous system (ANS). As a consequence, the hypothalamus regulates eating habits, sexual activity, and sleep patterns in addition to regulating the body temperature of a person. Additionally, the hypothalamus regulates the secretions of the pituitary gland, which arises from a downward extension of the hypothalamus.
