Brain Development Quiz

Brain region controlling voluntary movement.

Relay center for sensory information to the cortex.

Coordinates movement and balance.

Controls vital functions like breathing and heart rate.

Higher-level thinking, planning.

Region involved in speech production.

Region involved in language comprehension.

Maintains homeostasis, regulates hormones, emotions, and hunger.

Part of the brain containing most of the brain's mass, including the cerebrum.

A large band of neural fibers connecting the two brain hemispheres.

Ridges on the cerebral cortex.

Grooves or valleys on the cerebral cortex.

The front part of the brain. It's involved in higher-level functions.

Processes sensory information

Deep groove that separates the frontal and parietal lobes.

The process where the neural plate folds to form a hollow structure, the neural tube, which will develop into the brain and spinal cord.

Initial divisions of the developing brain: prosencephalon, mesencephalon, and rhombencephalon.

Further divisions of the primary vesicles: telencephalon, diencephalon, midbrain, metencephalon, and myelencephalon.

Bends in the developing brain due to growth constraints, crucial for shaping the brain's final form.

Spaces within the brain, extensions of embryonic neural canal, filled with cerebrospinal fluid (CSF).

Protective membranes surrounding the brain and spinal cord, consisting of dura mater, arachnoid mater, and pia mater.

Inflammation of the meninges, often caused by viral or bacterial infection.

Clear fluid that fills the brain ventricles and surrounds the brain and spinal cord. It provides cushioning and support.

A hollow tube formed during embryonic development from the folding of the neural plate. It gives rise to the brain and spinal cord.

The prosencephalon (primary brain vesicle) further divides into two secondary brain vesicles: telencephalon and diencephalon.

The rhombencephalon (primary brain vesicle) divides into two secondary brain vesicles: metencephalon and myelencephalon.

Cavities within the brain filled with cerebrospinal fluid (CSF). They are extensions of the embryonic neural canal.

Specialized cells that line the ventricles of the brain and the central canal of the spinal cord. They help circulate CSF.

The outermost layer of the meninges, a tough, protective membrane surrounding the brain and spinal cord.

A group of structures deep within the cerebrum, crucial for motor control and learning. They help with smooth, coordinated movements.

A part of the basal ganglia that includes the putamen and globus pallidus. It's involved in planning and executing movements.

A group of brain structures involved in emotions, memory, and motivation. It's like the emotional control center.

It's found in the medial aspect of each cerebral hemisphere and in the diencephalon. It's nestled deep in the brain around the center.

It helps us experience and regulate emotions, form memories, and motivates us to act. It's like our emotional compass.

The cerebrum is divided into four lobes: frontal, parietal, temporal, and occipital. Each lobe has specialized functions, such as controlling movement, processing sensory information, and interpreting language.

The corpus callosum is a thick band of nerve fibers that connects the two hemispheres of the brain, allowing them to communicate and share information.

The primary motor cortex, located in the frontal lobe, controls voluntary movements of skeletal muscles. It sends signals to muscles, initiating and coordinating actions.

The cerebellum, located at the back of the brain, coordinates movement, balance, and posture. It receives information from the brain and sensory organs to fine-tune movements.

The thalamus, located within the diencephalon, acts as a relay center for sensory information. It receives input from various senses and sends it to the appropriate areas of the cerebral cortex.

The hypothalamus, located below the thalamus, controls essential bodily functions like hunger, thirst, temperature regulation, and hormone release.

The developing brain forms four primary vesicles: prosencephalon (forebrain), mesencephalon (midbrain), and rhombencephalon (hindbrain). These further divide into secondary vesicles.

The medulla oblongata, located at the base of the brainstem, controls vital functions like breathing, heart rate, and blood pressure. It is essential for survival.

The telencephalon is the most developed part of the brain, responsible for higher cognitive functions. It includes the cerebrum, which makes up most of the brain's mass.

The corpus callosum is a thick band of nerve fibers that connects the two hemispheres of the brain, enabling communication and coordination between them.

Gyri are the ridges or folds on the surface of the brain, while sulci are the grooves or valleys between them. These structures increase the surface area of the brain, allowing for more neurons and processing power.

The four major lobes of the cerebrum are the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. Each lobe is responsible for different functions.

The central sulcus is a deep groove that separates the frontal lobe from the parietal lobe.

The parieto-occipital sulcus separates the parietal lobe from the occipital lobe, located at the back of the brain.

The deep lateral sulcus, also known as the Sylvian fissure, separates the temporal lobe from the frontal and parietal lobes.

Cranial fossae are depressions in the skull that house and protect parts of the brain.
