Where is the accessory cuneate nucleus?
The accessory cuneate nucleus is located lateral to the cuneate nucleus (Fig. 11.8). Its cells receive primary sensory input via cervical spinal nerves and project to the cerebellum as cuneocerebellar fibers.
What is the function of accessory cuneate nucleus?
The accessory cuneate nucleus is located lateral to the cuneate nucleus in the medulla oblongata at the level of the sensory decussation. It receives input from cervical spinal nerves and transmits that information to the cerebellum.
Where is the gracile nucleus?
dorsal medulla
The gracile nucleus, along with the cuneate nucleus, is a part of the dorsal column medial lemniscus pathway (DCML). The gracile nucleus situates in the midline dorsal medulla at the junction of the brainstem and the spinal cord.
Where is inferior cerebellar peduncle?
medulla oblongata
The upper part of the posterior district of the medulla oblongata is occupied by the inferior cerebellar peduncle (restiform body), a thick rope-like strand situated between the lower part of the fourth ventricle and the roots of the glossopharyngeal and vagus nerves.
Where is the fasciculus Cuneatus located?
The cuneate fasciculus (tract of Burdach), located laterally in the upper thoracic and cervical (C1 to T6) spinal cord segments, contains afferents from the upper trunk and extremities.
Where are the gracile and cuneate tracts?
Direct Dorsal Column Pathway The fibers that enter the spinal cord below the sixth thoracic segment form the gracile fasciculus (gracile tract), and fibers that enter the cord above the sixth thoracic segment are located laterally and form the cuneate fasciculus (cuneate tract).
Which part of the brain connects with inferior cerebellar peduncle?
cerebellum
Anatomical Parts Each cerebellar inferior peduncle connects the spinal cord and medulla oblongata with the cerebellum, and comprises the juxtarestiform body and restiform body.
What connects the cerebellum to the pons?
middle cerebellar peduncle
The middle cerebellar peduncle connects the transverse fibers of the pons with the cerebellum, which is entirely afferent to the cerebellum.
Where is nucleus gracilis and Cuneatus located?
In neuroanatomy, the dorsal column nuclei are a pair of nuclei in the dorsal columns in the brainstem. The name refers collectively to the cuneate nucleus and gracile nucleus, which are present at the junction between the spinal cord and the medulla oblongata.
Where is the gracile nucleus located?
The anatomic location of the gracile nucleus is on the floor of the fourth ventricle. The gracile nucleus gives rise to second-order neurons, which contain six different types of neurons. It is situated medially to the cuneate nucleus.
