MindMap Gallery Brain stem anatomy
This is a mind map about the structure of the brainstem. The main contents include: theme, the shape of the back of the brainstem, nerve distribution, and the shape of the abdomen of the brainstem. The introduction is detailed and the description is comprehensive. I hope it will be helpful to those who are interested!

brain stem structure
Appearance of brainstem abdomen
Medulla oblongata
Feature structure and definition
vertebral body
Longitudinal ridges on both sides of the anterior median fissure
olives
The oval bulge on the dorsolateral side of the upper vertebral body is called an olive
medullary pontine sulcus
vertebral body cross
At the lower end of the vertebral body, most of the corticospinal tract fibers cross left and right, forming a braided vertebral body crossover.
pons
base of pons
broad bulge on ventral side
basal sulcus
A longitudinal shallow groove on the midline of the base of the pons [accommodating the basilar artery]
middle cerebellar peduncle
The base narrows outward and rearward to form the middle cerebellar peduncle, also known as the pontine arm.
midbrain
cerebral peduncle
There is a thick longitudinal ridge on each side called the cerebral peduncle.
interfoot fossa
The depression between the cerebral crura on both sides is called the interpeduncular fossa, and the bottom of the fossa is called the posterior perforated substance [a small hole with many blood vessels entering and exiting]
Appearance of the back of the brainstem
Medulla oblongata
thin bundle tubercle
The lower part is shaped like a spinal cord, with two enlargements on each side of the posterior median sulcus, and a thin fasciculus tubercle on the medial side.
cuneiform tubercle
The outer surface is the cuneate fasciculus tubercle [the deep surface contains the core of the thin fasciculus and the cuneate fasciculus respectively, which are the termination nuclei of the thin fasciculus and cuneate fasciculus]
inferior angle of cerebellum
The bulge above and outside the tubercle of the cuneate bundle is the inferior cerebellar peduncle, also known as the cord-like body, and the fibers in it are connected backward to the cerebellum.
pons
superior cerebellar peduncle
The outer upper limit of the rhombus fossa, also known as the combined arm
The superior medullary velum is sandwiched between the two feet and participates in forming the roof of the fourth ventricle.
midbrain
Quadruplets
upper hill
visual reflex center
inferior colliculus
auditory reflex center
rhombus nest
The upper part of the medulla oblongata and the dorsal surface of the pons, also known as the floor of the fourth ventricle, are divided into upper and lower parts by the medullary stria.

theme
pontocerebellar triangle
In the lateral part of the medulla oblongata-pontine sulcus, the junction of the medulla oblongata, pons and cerebellum, is clinically called the pontocerebellar triangle. Vestibulocochlear neurofibromas can compress the facial nerve, trigeminal nerve, glossopharyngeal nerve, and vagus nerve.
