Medial Coronal section. Flashcards
Name this and state its function.
Corpus Callosum.
- Bundle of nerves connecting both cerebral hemispheres.
Name and state its function.
Lateral ventricles.
Name this and state its function.
Hippocampus.
- Ability to form new long term memories, especially spatial memory and direction.
Name this and state its function.
Thalamus.
- Gatekeeper and modulator of sensory inputs being sent to cortex.
Name this and state its function.
Third ventricle.
- Contain CSF fluid from lateral ventricle—->Third ventricle—>Fourth ventricle.
Name this and state its function.
Caudate nucleus.
- Controls voluntary skeletal movement.
- Further in learning, motivation, reward , etc…
Name this ,state its function and the name of the structures closely associated with it.
Putamen.
- Linked with the corpus striatum, involved in feedback loop to prepare and aid in movement of limbs.
Name this, state its function and its components[4 marks].
Globus Pallidus.
- Controls conscious and proprioceptive movements.
Components:
-
Gpe: intrinsic nucleus
- relays information.
-
Gpi: output nucleus.
- Outputs information to the thalamus.
Name this and state its function.
Crus Cerebri.
-
Connects both hemispheres to the cerebellum.
- Forming the middle cerebellar peduncle.
Name this and state its function. Also, state all 3 fibres involved.
Basilar pons.
- Provides information to the cerebellum through fibres.
- corticospinal fibres, corticonuclear, corticopontine.
Name this and state its function.
Claustrum.
- Theorised: processing of complex stimuli into consciousness??
Name.
Temporal horn of lateral ventricle.
Name this, state its function and consequence of lesion in this area.
Fornix.
- Transmits outgoing signals to the hippocampus via neurotransmitters with the main purpose of episodic memory.
Transmits Theta waves aswell.
Lesion: anterograde amnesia.
Name this and state its function. And what tract is involved?
Mamillary bodies.
- Project to the anterior nucleus of the thalamus( via mamillothalamic tract), with main functions of spatial and recollective memory.
