Back & Spinal Cord Flashcards
What 4 things does all connective tissue have in common
Cells, ground substance, fibers, mesenchyme origin (embryonic origin)
Stratified squamous epithelium with mitotic and amitotic layers
Epidermis
Mostly dense irregular connective tissue. Leathery
Dermis
What is another name for the hypodermis?
Superficial fascia
Connective tissue that separates, supports, and interconnects organs and structures
Fascia
Area of skin supplied by a single spinal cord level
Dermatome
Muscles which move the upper limbs and the ribs
Extrinsic
Deep muscles of the back. Maintain posture and move vertebral column
Intrinsic
What are the six movements of the scapula?
Superior/inferior rotation, elevation, depression, protraction and retraction (ab & adduction)
What 3 tissues make up the back?
Skeletal, smooth (parts of organs), cardiac (heart wall)
Which extrinsic muscle assists in rotating scapula during abduction of humerus
Trapezius
Which extrinsic muscle extends, adducts and medially rotates humerus
Latissimus dorsi
Which extrinsic muscles elevates the scapula
Levator scapulae
Which extrinsic muscle retracts and elevates scapula
Rhomboid major/minor
Which intermediate muscles elevates ribs two through five
Serratus posterior superior
Which intermediate muscles depress ribs/prevents elevation
Serratus posterior inferior
Which the muscles are primary extensors of the vertebral column/head and help control trunk flexion and lateral flexion
Erector spinae
Which deep muscles extend the spine and rotate short segments of the spine by pulling the spinous process close to transverse process
Transversospinales
Ligament directly posterior to vertebral body
Posterior longitudinal ligament
Which ligament is directly anterior to vertebral bodies
Anterior longitudinal ligament
Which ligament is between vertebrae articular processes
Ligamenta flava
Which ligament is between spinous processes
Interspinales
Which ligament is on top of or posterior along tips of the spinous processes
Supraspinous ligament
