What are the landmarks on the humerus?
On the humerus: the medial epicondyle (HME), the lateral epicondyle (HLE), and the lesser tubercle (HLT). On the ulna: the styloïd process (USP) and three points around the ulna head which averaged location gave an estimation of the ulna head center (UHE).
Where are the lacrimal bones located?
the orbit
There are two lacrimal bones, each of which is located in the medial wall of the orbit; they are hidden behind the nasal bone when looking at the skull from a frontal view. The orbits, or the eye-sockets, are the two bony cavities that enclose the eyeballs, as well as the muscles, blood vessels, and nerves of the eye.
What bone is the lacrimal foramen found?
The lacrimal bone and the frontal process of the maxilla build the lacrimal groove which contains the lacrimal sac. Posterior to the ethmoid bone, the medial wall is completed by a small portion of the lesser wing of the sphenoid bone that forms the medial part of the optic foramen (canal).
What is a fun fact about the humerus bone?
Speaking of long, the humerus is the longest bone in your arm. Despite its name, when you hit your “funny bone,” you’re not hitting your humerus. You’re actually hitting your ulnar nerve, which is located behind your elbow joint.
Which of the following is a bony landmark found on the proximal humerus?
Located on the lateral side of the proximal humerus is an expanded bony area called the greater tubercle. The smaller lesser tubercle of the humerus is found on the anterior aspect of the humerus.
What is lacrimal crest?
The anterior lacrimal crest is a bony projection on the frontal process of the maxilla in the skull. It reaches the junction between the maxilla and the lacrimal bone. At its junction with the orbital surface is a small tubercle, the lacrimal tubercle, which serves as a guide to the position of the lacrimal sac.
What is the lacrimal sulcus?
Lacrimal fossa (or lacrimal sulcus; fossa for lacrimal sac) – depression along the junction of the lacrimal bone and maxilla bone that holds the lacrimal sac; tears formed by the sac drain through a duct into the nasal cavity.
Is lacrimal fossa the same as lacrimal bone?
Specifically, the lacrimal bone helps form the nasolacrimal canal necessary for tear translocation. A depression on the anterior inferior portion of the bone, the lacrimal fossa, houses the membranous lacrimal sac. Tears or lacrimal fluid, from the lacrimal glands, collect in this sac during excessive lacrimation.
Which bony landmark is located on the lateral side of the proximal humerus?
Which of the following is a bone marking of the humerus?
| Location | Marking |
|---|---|
| Large projection located lateral to head | Greater tubercle |
| Lateral to the humeral head on anterior surface | Lesser tubercle |
| Groove located between the greater and lesser tubercles | Intertubercular sulcus (groove) |
| Roughened area located on the lateral aspect of the shaft of the humerus | Deltoid tuberosity |
What is posterior lacrimal crest?
The posterior lacrimal crest is a bony projection on the lacrimal bone which creates the medial margin of the lacrimal sac fossa.
Where is the lacrimal groove?
nasal
The lacrimal groove is a deep groove in front of the opening of the maxillar sinus on the nasal surface of maxilla, which is converted into the nasolacrimal canal, by the lacrimal bone and inferior nasal concha. This canal opens into the inferior meatus of the nose and transmits the nasolacrimal duct.
What is the lacrimal canaliculi?
Description. The lacrimal canaliculi (lacrimal canals; lacrimal ducts), are the small channels (about 1 cm) in each eyelid that commence at the puncta lacrimalia, on the summits of the papillae lacrimales, seen on the margins of the lids at the lateral extremity of the lacus lacrimalis.
What are the main bony landmarks?
The most observable are the head, neck, greater trochanter, lesser trochanter, linea aspera, condyles, and epicondyles. These landmarks function as parts of joints and muscle attachment points.
Which of the following landmarks is found on the proximal end of the humerus?
Which of the following landmarks found on the proximal end of the humerus? The greater tubercle is adjacent to the head of the humerus.
