What is the outer double-layered tough layer that anchors the CNS to the cranium or vertebral cavity?

What is the middle layer of the meningeal membrane?

What is the inner layer of the meninges that carries small blood vessels to nourish the underlying nervous tissue?

Cerebrum and Brain Structure

Largest part of the brain, involved in higher brain functions.
Surface features include gyri and sulci; gyri are the raised bumps, while sulci are the grooves.

Hemispheres and Fissures

Longitudinal fissure is a deep groove separating the brain's two hemispheres.
Transverse fissure separates the cerebrum from the cerebellum.

Lobes of the Cerebral Cortex

Frontal Lobe: Responsible for movement, abstract thinking, planning, memory, and judgment.
Parietal Lobe: Located at the top and rear, processes sensory input related to touch and body position.
Temporal Lobe: Found near the temples, primarily processes auditory information.
Occipital Lobe: Located at the back, responsible for visual information processing.

Cerebellum and Its Features

Known as "the little brain," situated at the lower back of the brain.
Vermis connects the two hemispheres of the cerebellum.
Folia are the folds of the cerebellum.

Colliculi and Corpora Quadrigemina

Superior Colliculi and Inferior Colliculi are responsible for visual and auditory processing, respectively.
Together, these structures comprise the corpora quadrigemina, located at the posterior brain stem.

Meningeal Layers

Dura Mater: Tough, outer layer with two layers; anchors the central nervous system (CNS) to the skull or vertebral cavity.
Arachnoid Mater: The middle layer of the meningeal membrane.
Pia Mater: Inner layer closely adheres to the brain, following its contours and supplies blood vessels to nourish the nervous tissue.

This quiz provides flashcard definitions for various parts of the brain as viewed from a superior perspective. Key terms include the cerebrum, gyrus, sulcus, and longitudinal fissure, giving a foundational understanding of brain anatomy. Ideal for students studying brain structure and function.
