Cerebrum Human anatomy and physiology

 Cerebrum anatomy and physiology:-




The cerebrum of the central nervous system is the upper most part of the brain. It is composed of basal ganglia, cerebral cortex and olfactory cortex. The cerebrum is divided into left and right hemispheres on either side of central fissures; the cerebrum is the largest part of the brain and handles the conscious thought and action area of the brain.


The cerebrum consists of the cerebral hemisphere and accounts for two thirds of the total weight of the brain. The hemisphere interprets visual and spatial information; it consists of the inner core of myelinated nerve fibres. The human cortex is several centimetres thick and has a surface area about 2000 square cm.


Anatomy of Cerebrum

Cerebrum is the largest and most developed portion of the human brain it was located in the upper most part of the brain the cerebrum may divided into two hemisphere they were cerebral cortices which was the outer layer.The two hemisphere were C shaped and then separated by deep longitudinal fissures the subcortical structure of the cerebrum includes basal ganglia, olfactory bulb and hippocampus.


Structure of Cerebrum





Parts of Cerebrum

There are two hemispheres in the cerebrum and the each hemisphere has four parts or lobes:

  • Parietal lobe: It is the middle part of the brain. The parietal lobe helps a person to identify objects and understand spatial relationships. They are sense, touch, pain, pressure etc.

  • Occipital lobe: It is the visual processing area of the brain associated with pseudo occipital processing distance. They're light, colour, and movement .

  • Temporal lobe: It sits behind the ears and is the second largest lobe. It is commonly associated with processing auditory information; they are memory, hearing, and understanding language.

  • Frontal lobe: It is the largest lobe in the human brain and they are also the most common region of injury in traumatic brain and voluntary movement of speech, emotion,body movement.


Functions or Physiology of Cerebrum



The cerebrum itself houses the four major lobes each lobe as its cerebrum has the numerous functions to control in the body cerebrum control voluntary function and action.

  • Sensory processing

  • Emotional control

  • Motor control

  • Personality

  • Learning

  • Imagination

  • Creativity

  • Spital information etc


The visual area and auditory area on the cerebral cortex is the centre vision of hearing. Association between various sensation and movement controlled in the frontal lobe.

Adrenergic neurotransmitters.

Adrenergic Neurotransmitters and Their Types Adrenergic Neurotransmitters and Their Types Adrenergic neurotransmitters are a crucial part of the human nervous system. They play a vital role in the transmission of signals between nerve cells and various target tissues. These neurotransmitters are derived from the amino acid tyrosine and have a profound impact on physiological responses. Types of Adrenergic Neurotransmitters Adrenergic neurotransmitters can be categorized into two main types: norepinephrine and epinephrine. 1. Norepinephrine Norepinephrine, often referred to as noradrenaline, is a neurotransmitter released by the sympathetic nervous system. It plays a key role in the "fight or flight" response, increasing heart rate, constricting blood vessels, and raising blood pressure. Norepinephrine also affects mood and arousal. 2. Epinephrine Epinephrin...

Myocardial Infraction.

Myocardial Infarction Myocardial Infarction What is Myocardial Infarction? Myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow to a part of the heart muscle is blocked for a prolonged period. This lack of blood flow causes damage or death to the heart muscle. The primary cause of myocardial infarction is the buildup of fatty deposits, or atherosclerosis, in the coronary arteries. Symptoms of Myocardial Infarction The symptoms of a myocardial infarction can vary from person to person. Common symptoms include: Chest pain or discomfort Pain in the neck, jaw, or back Pain or discomfort in the arms or shoulders Shortness of breath Nausea or vomiting Cold sweat Feeling lightheaded or dizzy It's important to note that not all people experience che...
