Answer 1

ANSWER :

1. Central Nervous System

• The central nervous system consists of two parts: Brain and Spinal cord. Brain is located in the bony skull where it is protected by three layers of tissues called 'menings'. The outer layer is called Dura matter and the innermost layer is called Pia matter. Brain is composed of white and grey matter, the white matter is called white because it is covered with a sheath known as mylin sheath.
• THE BRAIN is divided into three parts : Hind Brain, Mid Brain, Fore Brain.
• HIND BRAIN is the earliest part to develop in the evolution. It consists of Medulla, Pons, Cerebellum and Reticular formation. Medulla connects the spinal cord with brain. The function of this part of the brain is to control autonomous activities, collect informations about pain, sensation, temperature and heat. It also helps in coordinating the motor activities.
• MID BRAIN acts as a bridge between Fore Brain and Hind Brain. It has two divisions: Tactum and Tegmentum. It controls and collects auditory informations, sensory impulses, and motor impulses.
• Fore Brain is the most important part of the brain as it controls rational thinking, reasoning and memory. It is divided into two parts : Telencephalon and Diencephalon.
• THE SPINAL CORD carries information between the brain and the body.The spinal cord contains circuits that control certain reflexive responses, such as the involuntary movements your arm might make if your finger was to touch a flame.

2. Functions of Frontal Lobe

• The Frontal Lobe is responsibe for controlling important cognitive skills in human being such as memory, decision making, problem solving, language etc.
• It aslo plays a significant role in attention, motivation, and various other tasks of daily life.
• The Frontal Lobe controls the overall functioning of the Brain.
• It also pays a key role in self-management and future planning. Some of the other functions of Frontal Lobe are as follows :

1. Personality Formation : The Frontal Lobe helps in the formation of person's personality through control, memory and various other tasks and characterstics.
2. Language Production : The Frontal Lobe is responsible for understanding a language, ability to speak etc.
3. Memory Formation : The Frontal Lobe palys a key role in forming long-term memories.
4. Motor Skills : The Frontal Lobe is responsible for learning some motor skills which help in coordination and voluntary movemements.
5. Attention Mnagement : The Frontal lobe is efficient in managing attention as well.

3. Frontal Lobe Injury

• The frontal lobe injury may develop and affect each person differently. Some of the most common problems caused by the damage of the frontal lobe are as follows:

1. Poor Coordination: The overall functioning of the brain and the cognitive skills is perfomed by Frontal lobe. Hence, damage to this part results in very poor coordination and voluntary movements such as walking etc.
2. Language issues : The Frontal lobe is responsible for speech abilities, language skills etc. Hence, damage to this part may results in speech difficulties and disabilities.
3. Improper Decision Making : The Frontal Lobe plays a key role in future planning and problem solving, as well as decision making. Hence, damage to this part may result in poor self managent.
4. Personality changes : The damage to Frontal Lobe can result in changes in personality and a person's key characterstics.

4. Inability of regulating emotions, planning, decision making

• The inability to control emotions such as happiness, sadness, anger, joy, excitement etc can be both temporary and constant. People who suffer from the inability to control their emotions on a reguar basis and on a constant basis, are easily prone to a number of disorders such as Mood disorders, Depression, Mental Unstability etc. Various cognitive skills are really important for a healthy , positive life and better future, such as planning and decision making. Both of these are important aspects of a person's personality. The inability to plan and bad decision making may increase the chances of failure which ultimately leads to various mental disorders such as insomnia, depression, as well as certain mood and eating disorders.
