The elements in groups of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells. Going across a period from left to right, a proton is added to the nucleus and an electron to the valence shell with each successive element. Going down the elements in a group, the number of electrons in the valence shell remains constant, but the principal quantum number increases by...

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA The foot is a complex structure composed of numerous bones and articulations. It provides flexibility, is the essential contact point needed for ambulation, and is uniquely suited to absorb shock. Because the foot must support the weight of the entire body, it is prone to injury and pain. When examining the foot, it is important to remove shoes and socks on both sides, so that the entire foot can be inspected and compared.

FAQs
The lesser cornua provide distinct attachment relationships for the stylohyoid ligament and muscles that stabilize the hyoid apparatus. Because these projections arise where the hyoid body meets the greater cornu, they help connect stabilizing structures to a central part of the hyoid. This arrangement supports controlled movement during functions involving the neck and upper airway.
Their anatomical position and muscle attachments help maintain the hyoid apparatus as the tongue, larynx, and pharynx move in coordination. The lesser cornua do not act in isolation; instead, they provide anchoring points within a linked skeletal and muscular arrangement. Studying these relationships helps explain how hyoid support contributes to swallowing and speech.
Variation in the position or form of the lesser cornua can alter how their attachments are understood in an individual neck. This matters when relating the hyoid to nearby ligaments and muscles, especially during anatomical assessment. Recognizing variation helps prevent an unusual appearance from being mistaken for an injury or an unexpected structural relationship.
Their location on the hyoid and their connections with the stylohyoid ligament and stabilizing muscles make them useful anatomical reference points. During examination, understanding these relationships can help clinicians interpret the position and movement of the hyoid apparatus. This context is particularly relevant when assessing structures involved in swallowing, speech, or neck injury.
The lesser cornua provide landmarks for understanding the hyoid region on anatomical images and for considering possible structural disruption. Their normal position, relationship to the hyoid body and greater cornu, and associated attachments give context when an image or injury appears unusual. Anatomical variation must also be considered before assigning clinical significance to an observed difference.
They illustrate how a small skeletal projection can organize relationships among bone, ligament, and muscle. By examining the lesser cornua, students and researchers can connect hyoid anatomy with the coordinated movement of the tongue, larynx, and pharynx. They also provide a focused example of why anatomical landmarks matter in examination, imaging, and injury interpretation.
