ANATOMY

Detailed explanation-1: -The brain is composed of the cerebrum, cerebellum, and brainstem (Fig. 1). Figure 1. The brain has three main parts: the cerebrum, cerebellum and brainstem.

Detailed explanation-2: -Brainstem. The brainstem (middle of brain) connects the cerebrum with the spinal cord. The brainstem includes the midbrain, the pons and the medulla.

Detailed explanation-3: -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-4: -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. The hindbrain controls the body’s vital functions such as respiration and heart rate.

Detailed explanation-5: -The brain is a soft, spongy mass of nerve cells and supportive tissue. It has three major parts: the cerebrum, the cerebellum, and the brain stem. The parts work together, but each has special functions. The cerebrum, the largest part of the brain, fills most of the upper skull.
