Anatomy
Midbrain

Inferior colliculus
The inferior colliculus (IC) (Latin for ''lower hill'') is the principal midbrain nucleus of the Auditory system, auditory pathway and receives input from several peripheral brainstem nuclei in the auditory pathway, as well as inputs from the aud ...
, the principal midbrain nucleus of the auditory pathway

Superior colliculus
In neuroanatomy, the superior colliculus () is a structure lying on the tectum, roof of the mammalian midbrain. In non-mammalian vertebrates, the Homology (biology), homologous structure is known as the optic tectum or optic lobe. The adjective f ...
, a paired structure that forms a major component of the vertebrate midbrain

Collicular arteries
The collicular artery or ''quadrigeminal artery'' arises from the posterior cerebral artery. This small artery supplies portions of the midbrain, especially the superior colliculus, inferior colliculus, and tectum.

Anterior colliculus The anterior colliculus is the anterior portion of the medial malleolus of the distal tibia, forming part of the ankle

Posterior colliculus The posterior colliculus is the posterior portion of the medial malleolus of the distal tibia which is smaller in size comparing to the anterior colliculus. It has an attachment of the posterior tibiotalar ligament which is a part of deltoid ligamen ...

Seminal colliculus
The seminal colliculus (Latin ''colliculus seminalis''), or verumontanum, of the prostatic urethra is a landmark distal to the entrance of the ejaculatory ducts (on both sides, corresponding vas deferens and seminal vesicle feed into correspondin ...
, a landmark near the entrance of the seminal vesicles

Facial colliculus
The facial colliculus is an elevated area located in the pontine tegmentum (dorsal pons), within the floor of the fourth ventricle (i.e. the rhomboid fossa). It is formed by fibres from the facial motor nucleus looping over the abducens nucleus. ...
