Study Notes
The Cerebrum
- The cerebrum is the largest part of the brain, divided into two hemispheres: left and right.
- The surface of the cerebrum is called the cerebral cortex, a thin layer about 2-4 mm thick.
- The cortex has a surface area of 2,360 cm² and is composed mainly of glial cells, cell bodies, dendrites, and axons.
- The cerebral cortex gives the brain its characteristic gray-brown colour.
- The folding patterns of the cortex create bulges (gyri) and grooves (sulci and fissures).
- The fissures divide the cerebrum into five lobes: frontal, parietal, temporal, occipital, and the insula.
Temporal Lobes
- Located on the sides of the brain near the temples, separated from other lobes by the lateral sulcus.
- The transverse gyrus of the temporal lobe is the primary auditory area.
- The left temporal lobe is crucial for language comprehension.
- This lobe also plays a role in complex visual processing, including motion perception and facial recognition.
The Brain
- The brain is one of the largest organs in the human body, weighing approximately 1.4 kg in most adults.
- It contains about 100 billion neurons and 900 billion neuroglia.
- Most neuron growth occurs prenatally and during the first few months of life, with no significant increase after this period.
- Good nutrition during prenatal neuron development is crucial for brain growth.
- The brain continues to grow rapidly for the first 9 years of life and reaches its full size around 18 years.
- It is divided into three major parts: the forebrain, midbrain, and hindbrain.
Forebrain
- The forebrain consists of the telencephalon and the diencephalon.
- The telencephalon includes the cerebral cortex, basal ganglia, and limbic system.
- The diencephalon includes the thalamus, hypothalamus, optic chiasma, and pineal body.
Midbrain
- The midbrain is composed of the tectum and tegmentum.
Hindbrain
- The hindbrain includes the cerebellum, pons, and medulla oblongata, collectively known as the brainstem.
- The medulla oblongata is the lowest part of the brainstem, the midbrain is the highest, and the pons lies between the two.
