Neuroanatomy - Anatomy of the Cerebrum

Development of the telencephalon comes from the:

prosencephalon

What do clinicians think of the prosencephalon as?

forebrain

Since clinicians think of the prosencephalon as the forebrain, what other part of the brain must be included in the development of hte telencephalon?

Diencephalon

Ventricles in the telencephalon

lateral ventricle

Fissures of hte cerebrum

• transverse cerebral

• longitudinal cerebral

Transverse cerebral fissure

contains tentorium cerebelli composed of a fold of dura that imvaginates

longitudinal cerebral fissue

contains falx cereebri composed of a fold of dura

Sulci of the cerebrum

• lateral rhinal

• cruciate

This feature separates the rinencephalon from the rest of hte cerebrum

lateral rhinal

landmark for motor cortex

cruciate

Gyri of the cerebrum

• precruciate

• postcruciate

• lissencephaly

What does lissencephaly mean?

a brain that is really smooth

What are the lobes of the cerebrum named for?

the overlying bone of the skull

What are the lobes of the cerebrum

1. Frontal

2. Parietal

3. Temporal

4. Occipital

Frontal lobe functional association of cerebral lobe

motor cortex (and thought)

Parietal lobe functional association of cerebral lobe

sensory cortex

Temporal lobe functional association of cerebral lobe

auditory cortex (also memory, emotions)

Occipital lobe functional association of cerebral lobe

Visual cortex

Rhinencephalon is also known as

paleocortex

Olfactory pathway

1. olfactory nerve

2. olfactory bulb

3. piriform lobe
