human anatomy the spine this video illustrates one of the main parts of the human body the spinal cord or the vertebral column one can understand the intricacies of the movements of the vertebral column by getting familiar with the joints and bones and the set of complex muscles which make up the spinal cord the vertebral column in mammals is known as the backbone or the spine the vertebral column protects the spinal cord and even supports the head the spinal cord serves as a joint for the ribs and musculature of the back the spine is a cord light bony structure in the human body and other vertebrates human vertebral column is formed by cereal arranged units called the vertebrae and are inwardly placed this vertebral column extends from the base of the skull and constitutes the main framework of the trunk these vertebrae have a central Hollow position which is called the neural canal the spinal cord passes through this narrow canal the first vertebrae is called the Atlas and this atlas articulates the occipital condyle which is a kidney shaped convex surface found in the lower back part of the skull the entire vertebral column is differentiated into cervical thoracic lumbar sacral and coccygeal regions starting from the skull the human body consists of about 24 articulating or joints vertebrae that compose these three sections however in reality it consists of 33 vertebrae where the other five are fused to form the sacrum broadly the three main sections of the spine include the cervical spine da-rae explained and the lumbar spine the cervical spine begins with the base of the skull seven vertebrae make up the cervical spine which are small and delicate with eight pairs of cervical nerves it is these vertebrae that help in the movement of the head in the neck the thoracic spine is located in the chest area and contains 12 vertebrae these are connected to the rib which limits the flexibility of these vertebrae the ribs aid in the protection of many vital organs in the human body there is another float bone on the ventral midline of the thorax which is called the sternum the vertebrae in the lumbar spine in most people is five in number they are larger than the thorax or cervical spine they carry most of the body's weight and support flexibility and extension each of the vertebrae is supported by a fibrous disc known as the intervertebral discs that acts like cushions between the bones the body of the vertebrae provide a resting place for these fibrous disah's the vertebrae increase in size from the neck downwards that is from the second cervical to the first rig there is a slight decrease in the next three vertebrae and then again there is a gradual increase in size till the sacrum vertebra each fibrous disc is made up of two parts the annales is the hard outer layer of the vertebra it surrounds a sponge-like center called the nucleus there are four facet joints in each vertebrae one pear faces upwards stability to the spine is provided by interlocking with the adjacent vertebrae a bone called the sacrum lies just below the lumbar spine the sacrum is uniquely shaped the lamina covers the spinal canal it is a large hole in the center of the vertebrae the spinal nerve passes through them part of the spine bones seem to be projecting outside the spine and these can be felt while running hands down the back bone this part of the bone that projects outside is known as the spinous process the spinous process is paired with two transverse processes which are oriented at 90 degrees to the spinous process one on each side they provide attachment to the back muscles hope this gives you a fair understanding of the spine by the way if you haven't yet please go ahead and subscribe to our Channel eel earning for the latest update on high-end 3d Anatomy videos here
