It is highly flexible and very strong
What are the 5 gross functions of the vertebral column?
Centre of gravity for the body Attachments for bones Attachments for trunk muscles Protection and passage of the spinal cord Segmental innervation of the body
Which 2 parts of the spine become secondary concavities?
The cervical and the lumbar parts
When does the cervical part of the spine become a secondary concavity?
When a young child begins to lift up their head
When does the lumbar part of the spine become a secondary concavity?
When the child begins to stand up and walk
What is the spine’s shape called in the fetus? Describe more
The primary curvature - a figure of C. Anteriorly concave
What type of shape does the primary curvature have?
Anterior concave
What type of shape does the secondary cruvature have?
Posterior concave
In which parts of the spine is the primary curvature retained?
Thoracic, Sacral and Coccygeal
In what part of the spine can kyphoses be seen?
The thoracic part
What is kyphosis?
An abnormally increased posterior convexity of the thoracic spine.
What does concave mean?
Curves in - think of something caving in
What does convex mean?

What is lordosis?
An abnormal inward curvature (concavity) of the lumbar and cervical regions of the spine

The secondary curvature start to disappear due to remodelling and a fully continuous primary curvature re-establishes
How many vertebrae make up the vertebral column?
33
What are the 2 ‘assembles’ (types of vertebrae) that make up the vertebral column?
Discrete single vertebrae and fused vertebrae
What are discrete single vertebrae? how many of them are there?
Verterbrae all capable of individual movement. 25
What are fused vertebrae? how many of them are there?
Vertebrae that fuse together to give 2 innominate structures - sacrum (4-6 vertebrae, 5 is normal) and coccyx (4 vertebrae)
What are the coccyx vertebrae otherwise known as?
Coccygeal
What are facet joints formed between?
Between the neural arches (vertebral arches) of adjacent neural arches
What type of joints are facet joints?
Synovial joints
Where is the spinous process of the vertebral arch found?
It is the part that sticks out
What is the vertebral body of the vertebrae?
The main weight bearing part
