What part of the vertebrae make the vertebral canal?
- How and where do spinal nerves travel between the spinal cord and the periphery?
- How are spinal nerves named?
- What are the anterior rami?
- What are the posterior rami?
- What are the meninges and where are they found?

they innervated? Accurately locate them on another person.

HLTH 1020 WEEK 9 LECTURE 1 – Spine Bones
- THE SPINE / VERTEBRAL COLUMN
o Vertebrae
▪ 7 CERVICAL
• “Cervical: pertained to in your neck.”
• Responsible for:
o Neck muscles
o Diaphragm
o Deltoid (shoulder)
o Wrist
o Triceps
o Hand
, • “There are only 7 cervical vertebrae but 8 cervical nerves because cervical
nerve 1 (C1) comes out rostral to the first cervical vertebra and cervical nerve 8
(C8) comes out caudal to the seventh cervical vertebra.”
▪ 12 THORACIC
• “Thoracic: in your chest.”
• Responsible for:
o Intercostals
o Abdominals
o Ejaculation
▪ 5 LUMBAR
• “Lumbar: in your lower back.”
• Responsible for:
o Hips
o Quadriceps
o Hamstrings – knee
o Foot
▪ 5 SACRAL (FUSED)
• Responsible for:
o Penile erection
o Bowel and bladder
▪ 4 COCCYGEAL (FUSED)
• “Some people have 2 or 3.”
- FUNCTIONS of Spine
o Supports body weight
▪ “You cannot have the weight of your body transferred from your organs, even
through your muscles. The vertebral column is what bears our body weight.”
o Transmit forces through pelvis to lower limbs
o Carry and position head
o [Provides a] brace and helps manoeuvre upper limbs
▪ “For example, several muscles (e.g. rhomboids and trapezius) originate on the
vertebrae which stabilise the scapula.”
o Protect spinal cord
▪ “Vertebral column forms a continuous cage.”
- SPINAL CURVE DEVELOPMENT
o Normal curves:
▪ At 2 foetal months
• When born – ‘two curves’ in vertebral column
o “C-shape includes the sacrum & coccyx curling forward, and the thorax
curling forward.”
• ‘Babies can't stretch out fully in utero’
▪ At 6 foetal months
• Start to get cervical curves
o Allows lifting of head
▪ At newborn
