Mid-pons. Flashcards
Name this and state its function.
Transverse pontine fibres.
- Connect the cerebrum to the cerebellum, function of coordination of movement.
Name this and state its pathway.
Fourth ventricle.
Third ventricle–>4th ventricle–> subarachnoid space.
Name this and state its function.
Cerebellum.
Name this and state its function.
Pathways? types?
the function of the first pathway?
Superior cerebellar peduncle.
Efferent pathway:
- Sending signals from Deep cerebellar nuclei(2 pathways).
first —>= superior cerebellar peduncle
-
Deep cerebellar nuclei—->superior colliculus.
- Function: orientation of the head
- Deep cerebellar nuclei—> thalamus—> primary motor cortex & premotor cortex.
*
Name this and state its function.
What does it connect?
Middle cerebellar peduncle.
- Afferent pathway, cell bodies that give rise to the pontine nucleus. Controlateral pons.
- Connect the pons to the cerebellum.
Name this and state its function.
State all components it controls.
Medial longitudinal fasciculus.
- Connects 3 CN responsible for the extraocular muscles of the eye.
- Oculomotor(III),Trochlear(IV) and Abducens(VI)
- Also the vestibulocochlear nerve(VIII).
Name this and state its function.
Trigeminal nerve(root).
- Sensory and motor innervations of the face.
Name this and state its function.
Pathway.?
Pyramidal tracts.
- Voluntary control of the musculature of the body and face.
Descending Pathway: Motor fibres, carrying information from Cortex—>brain and spine–> lower motor neurons.
Name this and state its function.
Medial lemniscus.
- Second-order neurons of DCML pathway.
- Transports sensory spinothalamic information:
- proprioception, fine touch and vibration.
