How many structures are in the brain?
The brain is composed of three main structures , the cerebrum, cerebellum, and brain stem. The brain sends chemical and electrical signals throughout the body to regulate different biological functions and sense environmental changes. The brain communicates with the majority of the body through the spinal cord.

What is the anterior border of the parietal lobe?
The anterior border of the parietal lobe is demarcated by the central sulcus, and the posterior border is formed by an imaginary line that extends between the parietooccipital sulcus (superiorly) and the preoccipital notch (inferiorly). The inferior border is formed by the lateral sulcus (Sylvian fissure), while the superior boundary of the parietal lobe is formed by the medial longitudinal fissure that separates the two cerebral hemispheres.
How many lobes are there in the cerebral cortex?
The cerebral cortex is divided into six lobes: the frontal, temporal, parietal, occipital , insular and limbic lobes. Each lobe of the cerebrum exhibits characteristic surface features that each have their own functions. These lobes are not anatomically separated from one another by any barriers, but are physically continuous with each other, or interconnected via neural pathways in order to work together to process and synthesize information.
Which lobe is the most anterior?
The frontal lobe forms the most anterior portion of the cerebral hemisphere and is separated from the parietal lobe posteriorly by the central sulcus, and from the temporal lobe posteroinferiorly by the lateral sulcus (Sylvian fissure). The most anterior portion of the frontal lobe is known as the frontal pole.
Which part of the brain is responsible for processing emotional information?
The most rostral portion of the frontal cortex is known as the prefrontal cortex, which encompasses the superior, middle and inferior frontal gyri of the frontal lobe. It plays a crucial role in the processing of intellectual and emotional information, including aggression, and facilitates judgement and decision-making.
What are the three parts of the inferior frontal gyrus?
The inferior frontal gyrus is divided into three parts: i) the pars opercularis, ii) the pars triangularis , and iii) the pars orbitalis. Pars opercularis refers to the most dorsal part of the gyrus, pars triangularis is the middle triangularly-shaped part, while the pars orbitalis represents the most ventral part of the gyrus.

The prosencephalon, mesencephalon, and rhombencephalon will form the forebrain, midbrain, and hindbrain, respectively. Shortly after these form, in the fifth week of gestation, the prosencephalon and rhombencephalon undergo further divisions, ...
How many halves are there in the cerebral cortex?
The cerebral cortex is divided into two halves, or hemispheres. It is covered with ridges (gyri) and folds (sulci). The two halves join at a large, deep sulcus (the interhemispheric fissure, AKA the medial longitudinal fissure) that runs from the front of the head to the back.
What is the brain made of?
Weighing about 3 pounds in the average adult, the brain is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts. The brain itself is a not a muscle. It contains blood vessels and nerves, including neurons and glial cells.
How does the brain work?
The brain sends and receives chemical and electrical signals throughout the body. Different signals control different processes, and your brain interprets each. Some make you feel tired, for example, while others make you feel pain.

What is the difference between gray and white matter?
In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: The white matter is on the outside, and the gray matter sits within.
What organ controls memory, emotion, touch, motor skills, vision, breathing, temperature, hunger, and every other process?
The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

What are the four lobes of the brain?
Brain Lobes and their Functions. The brain is divided into four sections, known as lobes (as shown in the image). The frontal lobe, occipital lobe, parietal lobe, and temporal lobe have different locations and functions that support the responses and actions of the human body.
Why is it more common to injure the frontal lobe than the other lobes of the?
It is more common to injure the frontal lobe than the other lobes of the brain because the lobe is located at the front of the skull. The effects of damage to the frontal lobe often result in personality changes, difficulty controlling sexual urges, and other impulsive and risk-taking behaviors. The parietal lobe has several functions ...
What are the functions of the temporal lobe?
The temporal lobe. There are two temporal lobes located on both sides of the brain that are in close proximity to the ears. The primary function of the temporal lobes is to processing auditory sounds. Other functions of the temporal lobe include: 1 Since the hippocampus, or part of the brain responsible for transferring short-term memories into long-term memories, is located in the temporal lobe, the temporal lobe helps to form long-term memories and process new information. 2 The formation of visual and verbal memories. 3 The interpretation of smells and sounds.
What is the parietal lobe?
This lobe is responsible for processing sensory information from various parts of the body. Here are some of the functions of the parietal lobe: Sensing pain, pressure, and touch. Regulating and processing the body's five senses.
What is the temporal lobe?
Other functions of the temporal lobe include: Since the hippocampus, or part of the brain responsible for transferring short-term memories into long-term memories, is located in the temporal lobe, the temporal lobe helps to form long-term memories and process new information. The formation of visual and verbal memories.
What is the difference between right and left sided damage to the parietal lobe?
Damage to the parietal lobe can result in problems with spatial reasoning, reading, writing, understanding symbols and language. Right-sided damage to the parietal area can affect a person's ability to dress or groom his or herself. While left-sided damage can result in language disorders and disorders with perception.
