Functions of the brain.

The brain controls the functioning of the human brain as a living organism. Some of the vital functions include breathing, thinking, talking, sleeping, and eating. Some of the main parts of the brain that control these functions include the frontal lobe, occipital lobe, temporary lobe, Broca’s area, parietal lobe, and Wernicke’s area.

The primary functions of the brain include:

Learning and memory.

The brain is responsible for converting the experience one encounters to codes which are then stored. The experience can then be recalled at later times through remembering. It also controls the learning process through the help of senses, and it will influence the perception we have towards different things that they encounter. The frontal lobe is responsible for controlling the process of thinking and learning. The temporal lobe also stores data in the brain that will be used to recognize faces and language between people.

Language and calculations.

Language is an essential aspect of human beings controlled by the brain. Wernicke’s area is responsible for understanding language, while Broca’s area helps in the expression of the language. The parietal lobe is also responsible for different spelling words in human beings. The brain also controls our mathematical ability; hence, we can solve various puzzles we encounter. 

Planning.

The frontal lobe allows one to plan things through controlling attention, flexible thinking, emotion, and behavior control. As long as one is willing to make an effort, and they can learn and execute what one has planned and be able to foresee what can happen in different situations.

Sensory Perception.

The brain controls the five senses that human beings have, including smell, touch, hear, taste, and see. These are essential aspects that allow human beings to survive. The senses in the brain control also control internal signals that will help us sense danger, experience tension, run for safety, and alertness, among others. The occipital lobe is responsible for controlling vision, while the parietal lobe controls perception.

Emotional response.

The loci and neural in the brain control the mood that a human being can have at different times. Emotion is linked to cognition and health maintenance by controlling the immune system. The other critical systems in the body of human beings that are controlled by the brain include the nervous, respiratory, and digestive systems, among others. 

Functions of the spinal cord.

It is the primary nerve in the body, and other somatic nerves are connected to it. The spinal cord is divided into five central regions: the cervical, thoracic, lumbar, sacral, and coccygeal vertebrae. It performs functions such as: 

Performing reflective actions.

Reflex actions protect human beings from harm, including blinking, sneezing, coughing, and other automatic responses. The spinal cord is linked to the brain, responsible for controlling memory; hence, reflex actions are developed and stored. The brain will send signals through the spine to control how human beings respond to different situations. The spinal cord will manage the stimuli and make the various parts of the body react.

Carrying message signals.

The spinal cord connects the brain to other parts of the body. It is responsible for sending signals from the brain to other parts of the body. It is performed by various sensory receptors located in different body parts.

Returning sensory signals to the brain.

The signals that are experienced in other parts of the body are returned to the brain, which is then converted to impulses that the body can understand. That will then help us make decisions and react when feeling pain, movement, pressure, etc.

How the functions are similar.

They both control various responses in the body hence responsible for controlling the breath, sight, taste, touching, hearing, and other basic body functions. They also determine how signals will be relayed and transported to various sensory organs in the body.

How the functions are dissimilar.

The brain’s primary function is to control all the activities in the body, while the spinal cord links the brain to other parts of the body and helps to transport signals. The brain decides on what to do with the signals, and it sends responses to the various sensory organs in the body that the spinal cord will control. The spinal cord is linked to all body parts such as the head, neck, skin, hands, toes, legs, hips, and others. The brain will be responsible for storing different memories that will dictate the response to various signals and stimuli that will be transported through the spinal cord. The spinal cord will also carry nutrients and waste products from the brain and into the brain to ensure proper functioning.
