The document discusses attachments of skeletal muscles, comparing tendons and aponeuroses, and detailing specific types including abdominal, palmar, and scalp aponeuroses. It highlights the functions and structures of these connective tissues, including the impact of conditions like Dupuytren's contracture on the palmar aponeurosis. Various aponeuroses serve to connect muscles and bones or separate them within the body.

3. Comparison between tendon and aponeuroses
AponeurosesTendon
Broad sheet of connective tissue,
tendon like, connecting muscle to
other muscle or bone.
Dense regular connective tissue, that
attaches muscle to bone.
Sheet-likeCord-like

structures.

5. Abdominal Aponeurosis
The abdominal aponeuroses is a
thin but strong membranous
structure, the fibers of which are
directed downward and medially.
It is joined with that of the
opposite muscle along the middle
line, and covers the whole of the
front of the abdomen.

6. Palmar Aponeuroses
The palmar aponeurosis (palmar
fascia) invests the muscles of the palm, and
consists of central, lateral, and medial
portions.
Duputyren’s contracture
-It is fibrosis and shortening of the palmar
aponeurosis (due to decrease of its blood
supply)
-It results in fixed flexion of the “medial
four fingers”

7. Scalp Aponeuroses
The scalp aponeuroses called epicranial aponeuroses.
It is a tough layer of dense fibrous tissue which runs
from the frontalis muscle anteriorly to
the occipitalis posteriorly.
