Examples of shaft in the following topics:
-
- Immediately lateral to the
head is the neck that connects the head with the shaft.
- Located superiorly on the main shaft,
lateral to the joining of the neck, the greater trochanter is a projection to
which the abductor and lateral rotator muscles of the leg attach.
- Also located
on the main shaft, but inferiorly to the neck joint, is the lesser trochanter.
- The shaft descends in a slightly medial
direction that is designed to bring the knees closer to the body’s center of
gravity, increasing stability.
- Two key
features of the shaft are the proximal gluteal tuberosity to which the gluteus
maximus attaches, and the distal adductor tubercle to which the adductor magnus
attaches.
-
- Finally, the greater and lesser tubercles are
found at the most superior end of the main shaft of the humerus.
- Below this proximal region lies the shaft,
which is separated from the proximal region by the surgical neck, so termed as
this in an area of frequent fracture.
- A major feature of the shaft is the
deltoid tuberosity located laterally to which the deltoid muscle attaches.
-
- This principle is commonly used in motors, in which the loop is connected to a shaft that rotates as a result of the torque.
- Thus, the electrical energy from the current is converted to mechanical energy as the loop and shaft rotate, and this mechanical energy is then used to power another device .
- Incidentally, those forces are vertical and thus parallel to the shaft.
- Electrical energy from the current is converted to mechanical energy as the loop and shaft rotate, and this mechanical energy is then used to power another device.
-
- The shaft is the part of
the hair projecting from the surface of our skin.
- A round shaft results in straight and coarse
hair.
- An oval hair shaft is responsible
for wavy hair.
- A flat shaft causes curly hair.
-
- Inside are six tombs for nineteen bodies that were buried inside shaft graves.
- The shaft graves were deep, narrow shafts dug into the ground.
- Grave Circle A, Grave Shaft IV, Mycenae, Greece.
- Grave Circle A, Grave shaft V, Mycenae, Greece.
- Grave Circle A, Grave Shaft IV, Mycenae, Greece.
-
- The shaft of the clavicle acts as the
origin and attachment point for numerous muscles and ligaments.
- At the medial
end of the shaft the pectoralis major originates from the anterior surface, the
posterior surface gives origin to the sternohyoid muscle and the superior
surface the sternocleidomastoid muscle.
-
- A rib consists of a head, neck, and shaft.
- Finally, the shaft forms
the majority of the length of the rib as it curves around the thoracic cavity
forming the rib cage.
-
- Only our species has such a distinctive mushroom-capped glans, which is connected to the shaft by a thin tissue of frenulum (the delicate tab of skin just beneath the urethra).
- Chimpanzees, gorillas, and orangutans have a much less extravagant phallic design: more or less all shaft.
- The diameter of the glans where it meets the shaft is wider than the shaft itself.
- This results in the coronal ridge that runs around the circumference of the shaft.
-
- One or two main diaphyseal nutrient arteries enter the shaft obliquely through one or two nutrient foramina leading to nutrient canals.
- Except for a few with double or no foramina, 90% of long bones have a single nutrient foramen in the middle third of the shaft.
- Young periosteum is more vascular, has more metaphyseal branches, and its vessels communicate more freely with those of the shaft than adult periosteum .
-
- The shaft of the ulna is triangular and
numerus muscles involved in pronation and flexion of the forearm attach to its
surface.
- As with the ulna, the shaft of the radius is triangular in
shape and numerous muscles, including the protonator teres, attach to it.
