The shaft of a long bone- diaphysis The head(s) of a long bone- epiphysis
Tubercle
tubercle ;)
Each metacarpal bone consists of a base, a shaft, and a head. The base attaches to the carpal bones in the wrist, the shaft is the long middle portion of the bone, and the head connects to the phalanges in the fingers.
The head of the long bone is called the Epiphyseal.The long bone constists of a diaphysis and an epiphysis. The ends are epiphysis and the shaft is diaphysis.
The long head from infra-glenoid tubercle, the medial convers most of the posterior area of humerus and the lateral from a ridge above the spiral groove. That is for the brachii Or do you mean Surae?
bone marrow is in the center of the bone shaft
The greater tubercle is located on the humerus, a long bone of the body located in the upper arm. It serves as the point of insertion for several muscles in the arm and chest.
infraglenoid tubercle
A tuberacle is a small, rounded projection of a process formed where tendons or ligaments attach.
No, the shaft is not the longest portion of a long bone. The shaft is the main middle part of the bone, also known as the diaphysis. The long bones have a shaft (diaphysis), and two ends (epiphyses) that may be longer in length compared to the shaft.
Triceps muscle has got medial head, lateral head and long head. Long head has got the origin from the infraglenoid tubercle. That means, when you contract the triceps muscle, long head gets support from the scapula bone. That gives additional support for the muscle to do the the action of extension on the elbow joint.
