Each ligamentum flavum connects the laminae of two adjacent vertebrae. [2] [3] They attach to the anterior portion of the upper lamina above, and the posterior portion of the lower lamina below. [1] They begin with the junction of the axis and third cervical vertebra, continuing down to the junction of the 5th lumbar vertebra and the sacrum. [2 ...
The posterior incudal ligament plays an important role in the vibration of the middle ear bones: together with the anterior ligament of the malleus, it forms a pivotal axis around which the ossicles rotate. This rotation conveys vibrations from the tympanum to the oval window on the bony labyrinth (where they can be transduced into electrical ...
From a clinical standpoint, denticulate ligaments do not play a significant role in lumbar spinal stenosis when compared to issues such as disc herniations, facet hypertrophy, shape of spinal canal, size of spinal canal, ligamentum flavum hypertrophy, or degenerative joint disease resulting in bony osteophyte formation.

The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear.The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
The ligamentum flavum did not appear to alter the dynamic alterations in the dimensions of the spinal cord. Even after the intervertebral disc was removed, the ligamentum flavum did not appear to be a factor in the change in the dimensions of the spinal canal. [6] By understanding the magnitude of the role that ligamentum flavum hypertrophy ...

The ligaments of malleus are three ligaments that attach the malleus in the middle ear.They are the anterior, lateral and superior ligaments.. The anterior ligament of the malleus also known as Casserio's ligament [1] is a fibrous band that extends from the neck of the malleus just above its anterior process to the anterior wall of the tympanic cavity close to the petrotympanic fissure.
The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (also pinna) and the ear canal. [1] It gathers sound energy and focuses it on the eardrum ( tympanic membrane ).
