Now, that brings us to the key take-home messages
from this presentation.
First, skin, fascia, three layers of muscles
- superficial, intermediate and deep, neurovascular
structures, ribs, vertebral column and spinal
cord with its attendant meninges constitute
Back muscles principally attach to the skull,
vertebral column, the scapula region and the
Back muscles are arranged in three layers
- superficial, intermediate and deep.
Superficial and intermediate muscles are innvervated
by named anterior rami of spinal nerves with
the exception of trapezius which is a cranial
Deep muscles are innervated by unnamed, usually,
posterior rami of spinal nerves, certainly
an exception was the suboccipital nerve that
Four muscles constitute the suboccipital group.
We have two recti - major, minor and two obliques
- superior and inferior.
The rectus major and both obliques form the
borders of the suboccipital triangle and
for most part the innervation and blood supply
to the muscles of the back is segmental.
Thank you for following along throughout this
course. We have had great opportunities to
explore the complexity, the beauty and all
of human anatomy. We have looked at osteology,
we have looked at musculature and we have
looked at various neurovascular components
that collectively form and construct what
we know as a human being. The best
way to learn anatomy is to kind of break it
down into its components, understand the concepts
and once you have a firm mastery of the concepts
then you can start to build on layers of detail.
And certainly, we did not have time within
the scope of this course to get into a lot
of detail, but hopefully, I have prompted
your curiosity, your intellectual curiosity
and you will want to search out some of this
detail once you have a nice grasp of the
Thank you again and best wishes to you.
