Anatomy
Anatomy is the study of body
structures, their organization and
location . Ana-tomy literally means “to
cut”.

FASCIA
Fascia is a band of connective tissue,
primarily collagen, beneath the skin
that attaches, stabilizes, encloses, and
separates & and other internal organs.
Deep Fascia
Dense, organized connective tissue.
Devoid of fat.
Investing fascia
Extends from inner layer of deep
fascia between individual muscles
and neurovascular bundles.
Intermuscular septa
Extends from inner deep fascia to
bone to form compartments/
sleeves around muscles, nerves and
blood supply.
