Test 1 The Brain
The Brain
The brain is the most complex organ in the human body, responsible for controlling all bodily functions and behaviors. It is divided into several parts, each with its own unique functions.
Parts of the Brain
Cerebrum
Largest part of the brain
Divided into two hemispheres (left and right)
Responsible for conscious thought, voluntary movement, and sensory perception
Cerebellum
Located at the back of the brain
Responsible for balance, coordination, and fine motor skills
Brainstem
Connects the brain to the spinal cord
Controls involuntary functions such as breathing, heart rate, and digestion
Functions of the Brain
Frontal Lobe
Responsible for decision-making, problem-solving, and personality
Parietal Lobe
Processes sensory information such as touch, temperature, and pain
Occipital Lobe
Processes visual information
Temporal Lobe
Processes auditory information and is involved in memory and emotion
Disorders Associated with the Brain
Alzheimer's Disease
Affects the hippocampus and other parts of the brain
Causes memory loss, confusion, and difficulty with language
Parkinson's Disease
Affects the basal ganglia in the brainstem
Causes tremors, stiffness, and difficulty with movement
Stroke
Caused by a blockage or rupture of blood vessels in the brain
Can cause paralysis, speech difficulties, and cognitive impairment
Epilepsy
Caused by abnormal electrical activity in the brain
Can cause seizures, loss of consciousness, and cognitive impairment
Schizophrenia
Affects the frontal lobe and other parts of the brain
Causes hallucinations, delusions, and disordered think
