What is the long axis of a bone?

Diaphysis. – The shaft, or long axis, of the bone; constructed of a relatively thick collar of compact bone and surrounding a central medullary cavity.

n. A line parallel to an object lengthwise, as in the body the imaginary line that runs vertically through the head down to the space between the feet.

Similarly, what is long axis rotation? Longaxis rotation of the femur (up to 38 deg) modulated the foot’s transverse position. Longaxis rotation of the tibiotarsus (up to 65 deg) also affected medio-lateral positioning, but primarily served to either re-orient a swing phase foot or yaw the body about a stance phase foot.

Also asked, what is long axis of the tooth?

The long axis of a tooth is an imaginary line that goes through the crown and root around which the substance of a tooth is most symmetrically distributed. Any surface of a tooth that is parallel to the long axis is called an axial surface (for example, mesial, distal, facial, or lingual surfaces).

What is short axis view?

By rotating the transducer 90 degrees from PLAX in a clockwise direction you will obtain a parasternal shortaxis (PSAX) view. We define several shortaxis views, each cutting the heart at a different level between the base and the apex. When you rotate the transducer, the rotational axis is the mid-line of the sector.

What is the transverse axis?

The transverse axis is the axis of a hyperbola that passes through the two foci. The straight line joining the vertices A and A’ is called the transverse axis of the hyperbola. AA’ i.e., the line segment joining the vertices of a hyperbola is called its Transverse Axis.

What is the sagittal plane axis?

Sagittal axis – passes horizontally from posterior to anterior and is formed by the intersection of the sagittal and transverse planes. Frontal axis – passes horizontally from left to right and is formed by the intersection of the frontal and transverse planes.

What is the longitudinal axis of the body?

longitudinal axis. An axis along the lengthwise direction of the figure or body, usually passing through its center of gravity.

What movement occurs around the longitudinal axis?

Motion around the longitudinal axis, the lateral axis and the vertical axis are referred to as roll, pitch and yaw respectively. The primary flight control surface for controlling roll is the ailerons, for pitch the elevator and for yaw, the rudder.

What is a buckle on your tooth?

‘ When we check all around your mouth, we document the ‘state’ of your teeth and underlying gums. “This tooth needs a buccal,” means that a certain surface of the tooth needs it’s buccal surface filled. The word buccal means something though: it’s the surface of the tooth that is opposite the cheek.

Which teeth have a Cingulum?

The majority of a lingual surface’s cervical third is made up of the cingulum. On lower incisors, a cingulum usually is poorly developed or absent. Maxillary canines have a large, well-developed cingulum, whereas the cingulum of mandibular canines is smoother and rounded.

What is the cusp of the tooth?

A cusp is an occlusal or incisal eminence on a tooth. Canine teeth, otherwise known as cuspids, each possess a single cusp, while premolars, otherwise known as bicuspids, possess two each. Molars normally possess either four or five cusps.

What does MOD mean in dentistry?

MOD. Mesial-Occlusal Distal Facial

Which Teeth develop from 5 lobes?

While mandibular first premolars develop from four lobes (mesial, distal, buccal, and lingual) just like the anterior teeth and maxillary premolars, mandibular second premolars often develop from five lobes (mesial, buccal, distal, mesiolingual, and distolingual lobes).

What does facial mean in dentistry?

Facial. The side of a tooth that is adjacent to (or the direction toward) the inside of the lips, as opposed to lingual or palatal (both oral), which refer to the side of a tooth adjacent to (or the direction toward) the tongue or palate, respectively, of the oral cavity.

Is facial and buccal the same?

Facial – The surface that faces the cheeks or lips. Can also use the terms: Labial – The surface towards the lips. Buccal – The surface towards the cheeks.

What is occlusal surface?

“Occlusal” refers to the surface of the tooth that is used for chewing or grinding. Overall, there are five surfaces to each tooth: Occlusal. Mesial – forward or front. Distal – behind towards the back of the mouth.

What does OD mean in dental terms?

“D” stands for distal (the back surface). An “O,” which stands for occlusal, is the top surface of a back tooth. “I,” which stands for incisal, is the biting edge of incisors and canines (the front teeth). “B,” which stands for buccal, is the surface of the tooth that faces the cheek.
