What superior articular process of the sacrum articulate?
The superior articular process of the sacrum articulates with the inferior articular process of the last lumbar vertebra (L5) to form the lumbosacral joint.
What surface articulates Inferior process of the superior thoracic vertebrae?
There is no inferior process on any vertebrae, thoracic or not. There is an inferior articular facet. The inferior articular facet would articulate with the superior articular facet of the vertebrae just superior to it.
How do the superior and inferior articular process of the atlas differ from the same processes on a typical vertebra?
The surface of the superior articular will work right above the inferior surface in a vertebra. This is not true in the atlas.
Where are the apophyseal joints located?
The apophyseal joints are synovial joints in the vertebral column, between the superior or cranial articular process of one vertebra and the inferior or caudal articular process of the vertebra directly above it. See the link below:
Provides levers for the muscles to pull against?
superior articular process
Which axial skeletal bone has a small flat articular surface?
The axis (second cervical vertebra) has a small flat articular surface called the odontoid process or dens which articulates with the atlas (first cervical vertebra) to allow for rotation of the head.
Hypertrophy of the inferior articulating process?
Hypertrophy refers to the increase of the size of an organ, which can often be detrimental. The inferior articular process is a part of the vertebrae, and as such hypertrophy in this location can be extremely dangerous.
Where do ribs form a joint with the thoracic vertebrae?
headThe pedicle of the rib articulates with the transverse process of the thoracic vertebra.
What is the inferior most portion of the sternum?
The xiphoid process is the most inferior portion of the sternum. The superior section is the manubrium, and the medial portion is the body.
What is a zygapophysis?
A zygapophysis is a joint structure found in the vertebral column of animals, including humans. These paired processes help to stabilize the vertebrae and limit their movement by forming interlocking joints between adjacent vertebrae. They play a crucial role in providing support and facilitating movement in the spine.
What is the most inferior portion of the sternum?
The xiphoid process is the most inferior portion of the sternum. The superior section is the manubrium, and the medial portion is the body.
What cervical vertebra has a tooth-like projection on its superior surface?
The second cervical vertebra (C2), also called the axis, has a projection on it's superior surface called a dens that creates a pivot joint with the vertebra above it (C1), also known as the atlas. The pivot joint between these two vertebra allows 45 degrees of rotation in each direction, which is half the possible rotation of the head.
