Difference between typical and a typical vertebrae? The 'atypical' vertebrae are the two most superior positioned i.e. the top two (C1 & C2); C1 is also called the 'Atlas' and C2 the 'Axis'. The 'typical' vertebrae are the five most inferior positioned i.e. the bottom 5 (C3-C7).he spinal cord consists of 5 divisions or regions of vertebrae, in the cervical region (the most superior segment) along the spinal cord, are the 'typical' and 'atypical' v … ertebrae.

"What's the difference between ""typically"" and ""usually""?" I would also like to add another difference between the two. 'Typical' implies 'symbolic (of a particular type)', while 'usual' connotes 'habit/custom'. These are derived from the roots (typicalis and usus, respectively). So, if it is typical of a restaurant manager to come in early, it will be 'unusual' for him to be late on a particular day.

- The cervical spine (neck) is made up of a series of connected bones called vertebrae. The bones protect the spinal canal that runs through the vertebrae and carries the spinal cord. The spinal cord contains nerves that give strength and sensation to the arms and legs, and provide bowel and bladder control.Numerous con-nections (discs, joints, ligaments and muscles) between the cervical vertebrae provide sup-port, stability and allow motion.he spinal cord contains nerves that give strength and sensation to the arms and legs, and provide bowel and bladder control.

Spine Basics The first seven vertebrae form the cervical spine . The mid back, called the thoracic spine , consists of 12 vertebrae. The lower portion of the spine, called the lumbar spine , is usually made up of five vertebrae. However some people have a sixth lumbar vertebra. The normal spine has an S-like curve when looking at it from the side. This allows for an even distribution of weight.

Cervical Spine Anatomy (Neck) The cervical spine (sometimes abbreviated as c-spine in the medical world) begins at the base of the skull. Seven vertebrae make up the cervical spine with eight pairs of cervical nerves. The individual cervical vertebrae are abbreviated C1, C2, C3, C4, C5, C6, and C7.he cervical bones (the vertebrae) are smaller in size when compared to other spinal vertebrae (in your thoracic or lumbar spines). The purpose of the cervical spine is to contain and protect the spinal cord, support the skull, and enable diverse head movement (eg, rotate side to side, bend forward and backward).

An interview with Dr. Cunningham Degenerative changes of the vertebrae and disks that make up the spine are common in the aging population and may be associated with either osteoarthritis or osteoporosis. However, when these changes result in an asymmetry, a sideways curve of the spine measuring 10 degrees or greater, the condition is described as degenerative scoliosis.

- However, the natural curves should not be mistaken for spinal disorders also called Lordosis and Kyphosis. We will talk about abnormal curves later in this article. Figure 1 - A and B. Normal lordosis is the two forward curves seen in the neck (cervical spine) and low back (lumbar spine).Normal kyphosis is the two backward curves seen in the chest (thoracic spine) and hip areas (sacral spine).igure 2 - Scoliotic Curve. Curves are a normal part of the spine's structure. Looking at the spine from the side (lateral), several curves can be seen (Figure 1-A). From this angle, the spine almost resembles a soft 'S' shape.

- A small degree of both kyphotic and lordotic curvature is normal. The damaged endplate may take on an angled configuration that is associated with a kyphotic deformity. X-rays showed a severe kyphotic deformity of the cervical spine (Fig. 9 g, 135 mm, was doubly kyphotic, from V 6 to 12 and V 24 to 28.

- When a doctor assesses neck dystonia, they use a standard definition of normal posture to compare to the abnormal posture. This is called “ The standard anatomical position ”. In this position, a person is standing upright and facing forwards, feet together, and arms down by the side with palms facing forward.

Difference Between Compact and Spongy Bone Compact and spongy bones are considered the two basic structural bone types. The best explanation of the difference between the two is that the spongy bones in terms of area can be found at the head part of long bones. It also fills up the bones of an irregular type.pongy bones are also known as cancellous bones. Compact and spongy bones are the two main types of osseous tissues. Compact bones are made up of osteons. Osteons are also called Haversian systems. These osteons make the structure of compact bones.

X-rays of the Spine, Neck, or Back Anatomy of the spine. The spinal column is made up of 33 vertebrae that are separated by spongy disks and classified into distinct areas: The cervical area consists of 7 vertebrae in the neck. The thoracic area consists of 12 vertebrae in the chest. The lumbar area consists of 5 vertebrae in the lower back.

The different types of vertebrae Cervical. The first seven vertebrae, all in the neck. These are smaller and lightly built. Thoracic. Twelve vertebrae, each articulating with the twelve pairs of ribs. Lumbar. The lower five vertebrae, between the ribs and the sacrum.These have the largest vertebral bodies. Each of the three segments of the spine has a curve. The cervical spine and the lumbar curve both are convex anteriorly, while the thoracic spine curves the opposite way, convex posteriorly.Each vertebra is shaped a bit like a wedge to support these curves, especially noticeable with the five lumbar vertebrae.he first seven vertebrae, all in the neck.

Advanced Abdominal Imaging You have chosen to learn more about the Anatomy of the Spine. The spine is divided up into three major sections: the cervical, or neck, area; the thoracic section at chest level, and the lumbar spine of the lower back. When seen from the side, the three sections form the natural curves of the spine. When viewed from back to front, a healthy spinal column forms a straight line. Each section is made up of individual bones called vertebrae. There are 7 cervical, 12 thoracic, and 5 lumbar vertebrae. Each vertebra has a hole in the center of it, so when they are stacked on top of each other they form a hollow tube that protects the spinal cord and its nerve roots.

Normal Range of Motion in the Lower Back Side bending is called lateral flexion. The orientation of the facet joints in the lower back permits fairly free side bending. The normal range of motion in the lumbar spine is about 20 degrees to each side. Lateral flexion is primarily limited by tension in the ligaments and muscles on the opposite side of the spine.he orientation of the facet joints in the lower back permits fairly free side bending.

Spinal fractures Your spine is made of 33 bones called vertebrae that provide the main support for your body, allowing you to stand upright, bend, and twist. In the middle of each vertebra is a hollow space called the spinal canal, which provides a protective space for the spinal cord (Fig. 1).pinal instability: abnormal movement between two vertebrae that can cause pain or damage the spinal cord and nerves. vertebral compression fracture (VCF): a break in the vertebral body of the spine causing it to collapse and produce a wedge-shaped deformity.
