anatomical landmarks

Commonly used anatomical landmarks (ribs, aortic bifurcation (AB), right renal artery (RRA) and iliac crest height) were documented to determine the ability to correctly number the lumbar vertebrae.

What are anatomical landmarks used for?

Anatomic landmarks are used by surgical pathologists for specimen orientation and when lost (e.g., by tumour or trauma), make assessment of margin clearance or involvement by malignancy difficult.

What are bony landmarks?

Any place on the skin surface where the underlying bone is normally close to the surface and easily palpable.

What is a surgical landmark?

Surgical landmarks are used as guideposts to lead the surgeon safely to the facial nerve. The tragal cartilage “pointer” is a key landmark to help identify the main trunk of the extratemporal facial nerve.

What are the regions of the body?

The five regions of the body are the head, neck, torso, upper extremities, and lower extremities. The body is also divided by three imaginary planes known as the sagittal plane, coronal plane, and transverse plane. The sagittal plane runs vertically and divides the body into right and left portions.

What are the landmarks of the face?

We define a face landmark as a prominent feature that can play a discriminative role or can serve as anchor points on a face graph. Commonly used landmarks are the eye corners, the nose tip, the nostril corners, the mouth corners, the end points of the eyebrow arcs, ear lobes, nasiona, chin etc.

What are skull landmarks?

Skull landmarks of anatomic importance exist, located where there is a palpable bony protuberance or where sutures join: nasion. glabella. bregma. vertex.

Where are the bony landmarks?

Bony Landmarks
Iliac crest – the highest point of the pelvis, extending anterior to posterior.Anterior superior iliac spine – a sharp notch anterior to the iliac crest.Posterior superior iliac spine – the most posterior aspect of the iliac crest, identified by dimples at approximately the level of S2.

What are the landmarks of pelvis?

Pelvic Landmarks

What is the difference between tubercle and tuberosity?

Tubercle vs tuberosity

A tubercle is a small rounded prominence, often a site of tendon or ligament attachment e.g. adductor tubercle of the femur. A tuberosity is larger, found in varying shapes and often rough in texture.

Which is most important structure during parotid gland surgery?

The tympanomastoid suture was nearest to the main trunk and was therefore considered the most reliable landmark.

What is superficial parotidectomy?

A superficial (or lateral) parotidectomy involves removing all of the gland superficial to the facial nerve, whereas a partial superficial parotidectomy involves removing only the portion of the gland surrounding a tumor or mass.

What is studied in surface anatomy?

Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. In birds this is termed topography. Surface anatomy deals with anatomical features that can be studied by sight, without dissection.
