What is Tuberculum Cinereum?
Definition of tuberculum cinereum : an elevation on the lateral aspect of the medulla oblongata produced by the spinal trigeminal tract and its nucleus.
What is Tuberculum majus?
The larger tuberosity of the humerus at the upper end of its lateral surface, giving attachment to the infraspinatus, supraspinatus, and teres minor muscles.
Is the pituitary stalk hollow?
Your pituitary gland is about the size of a pea and is situated in a bony hollow, just behind the bridge of your nose. It is attached to the base of your brain by a thin stalk.
Are tubercle and tuberosity the same thing?
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.
What muscles attach to tubercle?
The greater tubercle is the most lateral bony point of the humerus and is palpable at the posterolateral aspect of the shoulder. The superior aspect of the greater tubercle is marked by three impressions that serve as attachment points for the supraspinatus, infraspinatus and teres minor muscles.
Does pituitary stalk enhance?
The pituitary stalk, also known as the infundibulum or infundibular stalk, is largely outside the blood brain barrier like the rest of the pituitary and therefore normally enhances following the administration of gadolinium.
Can you live without a pituitary gland?
You can live without your pituitary gland as long as you take medication to replace the pituitary hormones that you’re missing. The pituitary gland hormones are very important for maintaining several bodily functions. An untreated lack of all the pituitary hormones is life-threatening.
Is a trochanter a tubercle?
A trochanter is a tubercle of the femur near its joint with the hip bone. In humans and most mammals, the trochanters serve as important muscle attachment sites. Humans are known to have three trochanters, though the anatomic “normal” includes only the greater and lesser trochanters.
What is the difference between tubercle and spine?
is that spine is a person or thing’s backbone; the series of bones collectively from one’s (literal or figurative) head to tail or pelvis while tubercle is (anatomy) a round nodule, small eminence, or warty outgrowth, especially those found on bones for the attachment of a muscle or ligament or small elevations on the …
What muscles attach to lesser tubercle of humerus?
The subscapularis muscle originates at the subscapular fossa and inserts into the lesser tubercle of the humerus.
What inserts on greater tubercle of humerus?
The upper surface of the greater tubercle is rounded, and marked by three flat impressions: the highest (“superior facet”) gives insertion to the supraspinatus muscle. the middle (“middle facet”) gives insertion to the infraspinatus muscle.
