How Do You Spell RECESSUS ETHMOLACRIMALIS?

1. Recessus ethmolacrimalis is a term used in anatomy to describe a specific anatomical structure located in the human skull. It refers to a recess or cavity found in the ethmoid bone, which is a small, delicate bone located between the eye sockets and forming part of the nasal cavity.

   The recessus ethmolacrimalis is situated in the anterior part of the ethmoid bone and is closely associated with the lacrimal apparatus, which encompasses the structures responsible for the production, secretion, and drainage of tears in the eye. This recess serves as a passageway or channel that facilitates the drainage of tears from the eyes into the nasal cavity.

   Within the recessus ethmolacrimalis, there are small openings known as ethmoidal canaliculi, which connect the lacrimal sac, a dilation in the nasolacrimal duct, to the nasal cavity. These canaliculi provide a pathway for tears to flow from the lacrimal sac to the nasal cavity, ultimately allowing the tears to be drained away from the eyes.

   The recessus ethmolacrimalis plays a crucial role in tear drainage and is an essential component of the lacrimal apparatus. Without this structure, tears would not be able to drain properly, potentially leading to excessive tearing or watering of the eyes, a condition known as epiphora.

   Overall, the recessus ethmolacrimalis is an anatomical feature that contributes to the normal function of the lacrimal system by providing a pathway for tears to be drained from the eyes into the nasal cavity.

2. A cavity between the anterior portion of the ethmoid bone and the orbit.
