What are the three main parts of the brain developed during fetal growth?
Hindbrain, midbrain, and forebrain.
What is the primary function of the hindbrain?
It manages vital functions.
What does the midbrain coordinate?
It manages incoming information and coordinates sound and vision with muscle movement.
What are the two main components of the forebrain?
The diencephalon and the cerebral cortex.
What is the role of the diencephalon?
It manages incoming information and the endocrine system.
What is the cerebral cortex responsible for?
It it the largest and most complex brain region where decisions are made.
What structures protect the brain?
The skull, cerebrospinal fluid (CSF), blood-brain barrier, and meninges.
What are the three layers of meninges?
Dura mater, arachnoid mater, and pia mater.
What is the function of the medulla oblongata?
It manages autonomic functions such as breathing rate and heart rate.
What does the pons do?
It coordinates respiration and links the cerebellum to the rest of the brain.
What is the function of the cerebellum?
It manages learned movements and coordinates motor functions.
What is the role of the midbrain in the brainstem?
It connects the forebrain and hindbrain and manages information flow.
What is the corpus callosum?
A bridge between the two hemispheres of the brain.
What is the function of the thalamus?
It sends sensory information to the correct region of the cerebrum.
What does the hypothalamus regulate?
It controls the endocrine system and various autonomic functions.
What are the four lobes of the cerebral cortex?
Frontal lobe, partiel lobe, occipital lobe, and temporal lobe.
What is lateralization in brain function?
The left and right sides of the brain have different functional roles despite being structurally similar.
What functions are typically associated with the left hemisphere?
Language, logic, analytical tasks, and decision-making.
What functions are typically associated with the right hemisphere?
Visual-spatial skills, muscle creativity, and emotional context.
What are psychoactive drugs?
Drugs that have an effect on the brain, often influencing neurotransmitter functions.
What is a common treatment for Parkinson's disease?
L-Dopa, which is converted to dopamine.
What congenital defect is associated with impaired brain development?
Microcephaly.
What is Fetal Alcohol Syndrome?
A condition resulting from alchol exposure during pregnancy, leading to developmental issues.
What is the role of neurotransmitters in the brain?
They facilitate communication between neurons and influence various brain functions.
What is the function of the sensory areas in the cerebral cortex?
They process sensory information from the body.
What is the role of the prefrontal cortex?
It is involved in decision-making and planning responses.
