The Human Brain Parts
The subconscious brain is concerned with activities that take no thought but just are. Different parts of the brain care for other arenas, as you’ll soon learn. These portions are:
- Medulla oblongata
- Limbic system
- The Brain Stem
The medulla oblongata is located within the mind stem and holds the pathways of conversation between the spinal cord and the various sections of the brain. The medulla is used to send sensory data from one part of the brain to another, which in turn influences the other side of the body. This part of the brain stem controls the heart beat and the rhythm of breathing, and it regulates the dimensions of blood vessels. Minor operations of the medulla oblongata take care of the functions of swallowing, vomiting, coughing, sneezing, and hiccups.
The pons is the bridge that connects the spinal cord to the brain and various brain portions to each other. This part of the brain stem works with the medulla to assist regulating respiration.
The midbrain is another piece of the mind stem. This part deals with motor and sensory nerve bundles. These nerves lift impulses from the cerebral cortex to the pons and the spinal cord. The midbrain additionally accommodates nerves that conduct power to the thalamus.
This element of the mind comprises the thalamus, the hypothalamus, and the pineal gland. It is a transmitter to the cerebral cortex, relaying sensory data from different portions of the brain and the spinal cord. The thalamus component of the diencephalon translates and transfers sensory messages relating to pain, temperature, touch, and pressure. The pineal gland is that lentil-sized part that produces the hormone melatonin. Melatonin promotes sleepiness as well as regulating the circadian rhythms of the body.
The hypothalamus, even though small in size, conducts a majority of the business in the brain. This component of the diencephalon controls many activities related to homeostasis. Some of the purposes of the hypothalamus include:
- Regulation of heart rate, digestion, and release of urine.
- Reception of data from the inner organs.
- Connecting the nervous system and endocrine system.
- Production of hormones.
- Control of the pituitary
- Creating a center to maintain brain-over -body control.
- Establishing a connection between feelings and behavior.
- Control of body temperature.
- Regulation of food and fluid intake.
- Maintenance of sleep patterns.
The hypothalamus constantly receives data from inside and outside the body. This tiny area of the brain is an important part in maintaining balance throughout the body, keeping functioning at the best level.
Cerebrum and Cerebellum
The purpose as of the cerebrum is to maintain the areas of sensory impulses and muscular movement in addition to the areas of emotions and intellect. This center of control is divided into four sections in the lobes of the cerebrum. Each set of lobes has a selected function. Some of those include:
- Frontal lobes keep an eye on muscle contraction, learning ability, intellect, and emotion.
- Parietal lobes keep an eye on impulses of pain, cold, heat, touch, and pressure.
- Temporal lobes keep watch over hearing, smell, and language development.
- Occipital lobes regulate seeing and recognition of shape, color, and movement.
- These areas are controlled by the cerebrum, as are memories.
The cerebellum is a major region of the brain, coping with the subconscious movements of the muscles. This butterfly-shaped segment is the second largest part of the brain. The cerebellum deals with coordination, posture, and balance.
The limbic system is the area of the brain that surrounds the brain stem in a wishbone shape. This system is the emotional and behavioral center, known as the “emotional brain.” Certain areas of memory are controlled from the limbic center. Because feelings are connected to the memories, those memories with tough emotions are more often remembered.
