Anatomy of the Brain

What’s the central nervous system (CNS)?

The CNS consists of the mind and spinal wire. The mind is a vital organ that controls thought, reminiscence, emotion, contact, motor expertise, imaginative and prescient, respiration, temperature, starvation, and each course of that regulates our physique. The mind determines your persona and the way you work together with the setting, together with different individuals. This defines who you’re.

What are the completely different elements of the mind?

The mind may be divided into the cerebrum, brainstem, and cerebellum:

• Cerebrum. That is the entrance of the mind. It’s made up of the suitable and left hemispheres, that are joined by the corpus callosum. The cerebrum controls: initiation of motion, coordination of motion, temperature, contact, imaginative and prescient, listening to, judgment, reasoning, downside fixing, feelings, and studying. The cerebrum is answerable for communication (talking and writing), reminiscence, summary thought, and appreciation for music and artwork.

• Brainstem. That is the center of the mind. It consists of the midbrain, the pons, and the medulla. The brainstem controls motion of the eyes, face, and mouth. It additionally relays sensory messages (similar to sizzling, ache, and loud) and controls respirations, consciousness, cardiac perform, involuntary muscle actions, sneezing, coughing, vomiting, and swallowing.

• Cerebellum. That is the again of the mind. It coordinates voluntary muscle actions and helps to keep up posture, stability, and equilibrium.

Extra particularly, different elements of the mind embrace the next:

• Pons. A deep a part of the mind, positioned within the brainstem, the pons comprises lots of the management areas for eye and face actions.

• Medulla. The bottom a part of the brainstem, the medulla is probably the most important a part of the whole mind and comprises essential management facilities for the guts and lungs.

• Spinal wire. A big bundle of nerve fibers positioned within the again that extends from the bottom of the mind to the decrease again, the spinal wire carries messages to and from the mind and the remainder of the physique.

• Frontal lobe. The most important part of the mind positioned within the entrance of the top, the frontal lobe is concerned in persona traits and motion. Recognition of odor usually entails elements of the frontal lobe.

• Parietal lobe. The center a part of the mind, the parietal lobe helps an individual to establish objects and perceive spatial relationships (the place one’s physique is in comparison with objects across the particular person). The parietal lobe can also be concerned in decoding ache and contact within the physique.

• Occipital lobe. That is the again a part of the mind that’s concerned with imaginative and prescient.

• Temporal lobe. The edges of the mind, these temporal lobes are concerned in short-term reminiscence, speech, musical rhythm, and some extent of odor recognition. The temporal lobes are additionally essential in understanding sound and voice.
