It's weird if you think too hard about it.

Calyx of Held

Calyx of Held

A large synapse in the mammalian auditory central nervous system, so named by German physician Hans Held in 1893 because of its resemblance to the calyx of a flower. The related endbulb of Held is also a large axon terminal smaller synapse found in other auditory brainstem structures such as the cochlear nucleus. As with the calyces, these synapses promote fast, efficient information transfer.




 Angle of Lewis

Angle of Lewis

The sternal angle, the anatomical feature formed from the manubriosternal junction (the joint of the sternal body and the manubrium). The angle is a palpable clinical landmark in surface anatomy, measuring around 162 degrees in males; it marks the approximate level of the second pair of costal cartilages, which attach to the second ribs. Named after 18th-century French surgeon and physiologist Antoine Louis, who is also credited with designing a prototype of the guillotine that, for a time... Read more...




 Descemet's membrane

Descemet's membrane

The posterior lining membrane of the eye's cornea; a thin hyaline (glassy and translucent) membrane between the substantia propria and the endothelial layer of the cornea.




 Organ of Corti

Organ of Corti

Also called the Spiral Organ; a complex epithelial structure in the cochlea of the mammalian ear that contains thousands of hair cells, rests on the internal surface of the basilar membrane, and is the chief part of the ear by which sound waves are perceived and converted into nerve impulses that are transmitted to the brain.

Italian anatomist Alfonso Giacomo Gaspare Corti discovered the organ of Corti in 1851 after studying at least 200 cochleas of man and different animals.




 Broca's area

Broca's area

Also called the convolution of Broca; a region in the frontal part of the dominant hemisphere of the brain, usually the left, that contains neurons involved in speech function.

French surgeon Paul Broca discovered this region's role in generating articulate speech in 1861, after studying two patients who'd lost the ability to speak when they sustained injuries to the posterior inferior frontal gyrus (pars triangularis) of their brains.




 Bachmann's bundle

Bachmann's bundle

A branch of the heart's anterior internodal tract on the inner wall of the left atrium. This band of cardiac muscle passes from the right atrium between the superior vena cava and the ascending aorta. During normal sinus rhythm, this is the path for the left atrium's electrical activation.

Bachmann's bundle was named for Jean George Bachmann, who discovered via canine experiments that that clamping this muscular bundle of fibers caused a significant conduction delay in the heart.





 Eustachian tube

Eustachian tube

The auditory or pharyngotympanic tube, which links the nasopharynx to the middle ear and is part of the latter. It was named after the 16th-century... Read more...




 Adam's apple

Adam's apple

A laryngeal prominence of the human neck, formed by the angle of the thyroid cartilage surrounding the larynx; seen especially in males. The origin... Read more...




 Achilles tendon

Achilles tendon

The large and prominent tendon of the gastrocnemius and soleus muscles of the calf, named, of course, after the Greek hero of the Trojan War, said... Read more...
