Brain Region Development: Telencephalon through Rhombencephalon

A set of QUESTION_AND_ANSWER flashcards covering the major brain divisions and their key structures.

What makes up most of the cerebrum and includes the Cerebral Cortex, Basal Ganglia, Hippocampus, Amygdala, and Olfactory bulb?

Telencephalon

What is the prosencephalon?

The forebrain; divides into the diencephalon and telencephalon.

What is the diencephalon and which major structures does it include?

Sits under the telencephalon; includes the thalamus, hypothalamus, epithalamus (pineal gland), and subthalamus.

What does the prefix 'tele-' (as in telencephalon) mean?

Far; farthest forward.

What is the mesencephalon?

The midbrain; includes the tectum (superior and inferior colliculi), tegmentum (red nucleus, substantia nigra), cerebral peduncles, and the cerebral aqueduct.

Where are Parkinson's disease symptoms linked to a dopamine deficiency?

In the mesencephalon, specifically the substantia nigra of the midbrain.

What is the metencephalon and what structures does it include?

Below the mesencephalon; includes the pons and cerebellum.

What is the myelencephalon and which structure does it include?

Under the metencephalon, above the spinal cord; includes the medulla.

What is the rhombencephalon?

The hindbrain; divides into the metencephalon and myelencephalon.

Why is the rhombencephalon named 'diamond-shaped'?

Rhombus = Diamond; it refers to the diamond-shaped arrangement of regions in the hindbrain.
