Study Notes
Structure and Function
- The vertebral column, also known as the spine, is a flexible yet strong structure forming the axial skeleton's central support.
- It extends from the skull to the pelvis, supporting the head and trunk and protecting the spinal cord.
- The spine comprises individual bony vertebrae stacked upon each other, separated by intervertebral discs.
- The vertebrae's shape and size vary along the spine to accommodate changing weight distribution and movement needs.
Types of Vertebrae
- Cervical vertebrae (7): These are the smallest and most delicate vertebrae, allowing significant neck mobility.
- Thoracic vertebrae (12): These are larger than cervical vertebrae and articulate with the ribs, connecting the spine to the chest cavity.
- Lumbar vertebrae (5): These are the largest and strongest vertebrae, supporting the majority of the body's weight.
- Sacrum (5 fused vertebrae): A triangular bone formed by the fusion of five sacral vertebrae, this structure provides stability for the pelvis.
- Coccyx (3-5 fused vertebrae): The coccyx is a small, triangular bone at the inferior end of the spine, often called the tailbone.
Intervertebral Discs
- Intervertebral discs are located between each vertebra and consist of an outer fibrous annulus and an inner gelatinous nucleus pulposus.
- These discs act as shock absorbers, preventing jarring and excessive stress on the vertebrae.
- They enable flexibility in spinal movement and contribute to resilience against impact.
Curvatures of the Spine
- The spine exhibits four natural curvatures: cervical (lordosis), thoracic (kyphosis), lumbar (lordosis), and sacral (kyphosis).
- These curvatures maximize the spine's ability to absorb forces and maintain balance.
Spinal Cord
- The spinal cord, a critical nervous system component, passes through the vertebral canal formed by the vertebrae.
- It transmits signals from the brain to the body, facilitating motor control, sensory perception, and reflex actions.
- Nerves branch off the spinal cord at various levels, servicing specific areas of the body.
Ligaments and Muscles
- Numerous ligaments connect the vertebrae, maintaining the spinal column's support and stability.
- Deep and superficial muscles support the spine, enabling movement and posture.
- These muscles are essential for balance and movement control.
Clinical Considerations
- Spinal injuries range from minor sprains/strains to fractures and significant spinal cord damage.
- Spinal cord injuries can cause paralysis, loss of sensation, and other neurological complications.
- Degenerative conditions, like osteoarthritis and spinal stenosis, can cause pain and limit spinal movement.
- Maintaining good posture and regular exercise can help prevent spinal issues.
Developmental Aspects
- The spine's embryonic development is vital to its future structure and function.
- This development includes the formation of vertebral bodies, neural arches, and intervertebral discs.
- Various genetic and environmental factors can influence this developmental process and result in spinal abnormalities.
