Century Dictionary and Cyclopedia
- n. A partition, composed of a strong sheet of the dura mater, stretched across the back part of the cranial cavity in man, between the cerebrum and the cerebellum. A tentorium sometimes ossifies, or includes a shelf of bone, the bony tentorium, as in the cat family. More fully called
- n. In zoology and anatomy, the endocranium.
- n. Same as tenture.
- n. The framework of internal supports (a false endoskeleton) within an arthropod head, formed by ingrowths of the exoskeleton called apophyses.

“For there is a very marked groove in every such skull, as in the human skull -- which indicates the line of attachment of what is termed the 'tentorium' -- a sort of parchment-like shelf, or partition, which, in the recent state, is interposed between the cerebrum and cerebellum, and prevents the former from pressing upon the latter.”
“He said there was blood both above and below a part of the brain known as the tentorium, meaning that structure had to be injured, which is characteristic of birth trauma.”
“The occipital lobe is positioned on a process of the dura mater, known as the tentorium cerebelli, which divides the cerebrum from the cerebellum.”
“The occipital lobe is positioned on a process of the dura mater, known as the tentorium cerebelli, which divides the cerebellum.”
“The occipital lobe is positioned on a process of the dura mater, known as the tentorium cerebelli, which divides the [[cerebrum]] from the [[cerebellum]]”
“In the lower placental mammals, the cerebral hemispheres leave the proper upper and posterior face of the cerebellum completely visible, when the brain is viewed from above; but, in the higher forms, the hinder part of each hemisphere, separated only by the tentorium (p. 281) from the anterior face of the cerebellum, inclines backwards and downwards, and grows out, as the so-called”
“And I was the more inclined to suspect this, as, in ordinary human skulls, the occipital protuberance and superior semicircular curved line on the exterior of the occiput correspond pretty closely with the ‘lateral sinuses’ and the line of attachment of the tentorium internally.”
“Now in man, in all the old-world, and in all the new-world Simiae, with one exception, when the face is directed forwards, this line of attachment of the tentorium, or impression for the lateral sinus, as it is technically called, is nearly horizontal, and the cerebral chamber invariably overlaps or projects behind the cerebellar chamber.”
“But on the tentorium rests, as I have said in the preceding Essay, the posterior lobe of the brain; and hence, the occipital protuberance, and the curved line in question, indicate, approximately, the lower limits of that lobe.”
“For there is a very marked groove in every such skull, as in the human skull — which indicates the line of attachment of what is termed the ‘tentorium’ — a sort of parchment-like shelf, or partition, which, in the recent state, is interposed between the cerebrum and cerebellum, and prevents the former from pressing upon the latter.”
