Detailed explanation-1: -The brain can be divided into three basic units: the forebrain, the midbrain, and the hindbrain. The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum.
Detailed explanation-2: -The human brain is primarily composed of neurons, glial cells, neural stem cells, and blood vessels. Types of neuron include interneurons, pyramidal cells including Betz cells, motor neurons (upper and lower motor neurons), and cerebellar Purkinje cells.
Detailed explanation-3: -Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. Cerebellum: is located under the cerebrum. Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.
Detailed explanation-4: -Midbrain: The top part of the brainstem is crucial for regulating eye movements. Pons: The middle portion of the brainstem coordinates facial movements, hearing and balance. Medulla oblongata: The bottom part of the brainstem helps regulate your breathing, heart rhythms, blood pressure and swallowing.
