You probably meant the fossa above the jugular notch of the manubrium of the sternum in-between the sternal heads of the sternocleidomastoid muscles.
22.
The medusae brood pouch; the gonads either surround the manubrium entirely or are carried on manubrial extrusions or ( if present ) the brood pouch.
23.
The sternal head is a round fasciculus, tendinous in front, fleshy behind, arising from the upper part of the front of the manubrium sterni.
24.
The manubrium ( handle ) of the malleus articulates with the tympanic membrane, while the footplate ( base ) of the stapes articulates with the oval window.
25.
The malleus receives vibrations from sound pressure on the eardrum, where it is connected at its longest part ( the manubrium or handle ) by a ligament.
26.
It connects the tip of the costal cartilage to the fibrous junction between the manubrium and the body of the sternum, dividing the joint into two parts.
27.
The muscle arises from the posterior border of the medial end of the clavicle, the posterior sternoclavicular ligament, and the upper and posterior part of the manubrium sterni.
28.
The sternum is composed of highly vascular tissue, covered by a thin layer of compact bone which is thickest in the manubrium between the articular facets for the clavicles.
29.
The unique double-hinged articular disk found at the junction of the clavicular head and manubrium allows for movement between the clavicle and the disk during elevation and depression of the scapula.
30.
When the eardrum is moved inward due to sound vibrations, transferred through the outer ear, it transmits to the handle or manubrium of the malleus which is connected to the ear drum.
