Coronal section of the brain at the level of the thalamus

This tutorial explores the anatomy of the brain through coronal sections, focusing on gray and white matter structures, cortical regions, and ventricles. It highlights the thalamus as a major landmark and discusses the roles of various brain structures in sensory and motor functions. The tutorial also covers clinical correlations, such as Parkinson's disease, and concludes with a summary of key points.

What is a coronal section of the brain?

• A horizontal slice dividing the brain into upper and lower parts

• A vertical slice dividing the brain into anterior and posterior parts

• A diagonal slice dividing the brain into left and right parts

• A circular slice dividing the brain into inner and outer parts

Which structure is known as the 'Traffic Control Centre' of the brain?

• Substantia nigra

• Thalamus

• Caudate nucleus

• Subthalamus

What is the primary function of the basal ganglia?

• Producing cerebrospinal fluid

• Processing visual information

• Controlling movement

• Regulating emotions

Which structure is the largest collection of white matter fibers in the human brain?

• Fornix

• Corpus callosum

• Optic tract

• Internal capsule

What is the function of the fornix in the brain?

• Carries visual signals to the occipital lobes

• Connects the left and right cerebral hemispheres

• Transmits information from the hippocampus to the mammillary bodies

• Separates the thalamus from the lenticular nucleus

Which capsule is located between the putamen and the claustrum?

• Optic capsule

• Extreme capsule

• External capsule

• Internal capsule

What is the insular cortex responsible for?

• Connecting the two thalami

• Producing cerebrospinal fluid

• Regulating movement

• Processing sensory information

Which part of the brain is responsible for memory creation?

• Substantia nigra

• Hippocampus

• Insular cortex

• Cingulate gyrus

What is the role of the choroid plexus?

• Producing cerebrospinal fluid

• Connecting the cerebral hemispheres

• Regulating emotions

• Transmitting motor signals

In Parkinson's disease, which cells begin to die off?

• Pigmented cells of the substantia nigra

• Cells in the corpus callosum

• Cells in the thalamus

• Cells in the hippocampus
