Vertebral Column Flashcards
What is cartilage?
A flexible connective tissue found in various parts of the body
Cartilage provides support and cushioning in joints.
What are ligaments?
Tissue that connects bones to other bones at joints
Ligaments provide stability to the skeletal system.
What is the meniscus?
A C-shaped cartilage structure in the knee joint
The meniscus acts as a cushion and stabilizes the joint.
What is synovial fluid?
A viscous fluid found in joint cavities
Synovial fluid lubricates joints and reduces friction.
What is the joint capsule?
A fibrous tissue that surrounds a synovial joint
The joint capsule helps maintain joint stability.
What is a bursa?
A small fluid-filled sac that reduces friction between tissues
Bursae are located around joints and help facilitate movement.
What is the synovial membrane?
A thin layer of tissue that lines the joint capsule
The synovial membrane produces synovial fluid.
How many irregular bones make up the vertebral column?
33 irregular bones called vertebrae
The vertebral column provides structure and support to the body.
What percentage of a person’s overall height does the vertebral column account for?
Around 40%
This highlights the importance of the spine in overall body structure.
What are the five sections of the vertebral column?
- Cervical
- Thoracic
- Lumbar
- Sacral
- Coccyx
Each section has unique characteristics and functions.
How many cervical vertebrae are there?
7 vertebrae
The cervical vertebrae are located in the neck region.
What is the name of the first cervical vertebra?
Atlas (C1)
The Atlas supports the head and allows for nodding motion.
What is the name of the second cervical vertebra?
Axis (C2)
The Axis allows for rotational movement of the head.
How many thoracic vertebrae are there?
12 vertebrae
Thoracic vertebrae articulate with the ribs.
What is the structure of lumbar vertebrae?
5 largest vertebrae with a concave curve
Lumbar vertebrae support the weight of the upper body.
