Slide 24
Platysma
Slide 25
Anatomically the platysma appears to be a muscle of upper chest and lateral neck, it is actually a facial muscle.
Slide 26
Sternocleidomastoid muscle.
Slide 27
Sternocleidomastoid muscle on model.
Slide 28
Pectoralis major, a muscle of upper arm and not a muscle of respiration.
Slide 29
Pectoralis minor, a muscle of upper arm and not a muscle of respiration.
Slides 30
Serratus anterior (magnus),
a muscle of upper arm and not a muscle of respiration.
Slides 31
Serratus anterior (magnus),
a muscle of upper arm and not a muscle of respiration.
Slides 32
Schematic drawing of abdominal muscles.
*From Eileen and W. Zemlin, Study Guide/Workbook to Accompany Speech and Hearing Science, 4th ed., 1997 Stipes Publishing Co..
Slides 33
Internal intercostal muscles, which course down and laterally in front, occupy the chondral and adjacent osseus portion of the rib cage.
External intercostal muscles are seen lateral to internal intercostal muscles coursing downward and medially directed in front.
Note the auxiliary artery (red) and vein (blue), and brachial plexus (white.)
Slides 34
Muscles adjacent to the sternum (on the left) are internal intercostal muscles. Muscles coursing at opposite directions to the right of the center are external intercostal muscles.
Slides 35
Internal intercostal muscles have been removed revealing internal thoracic arteries (red) and veins (blue) lateral to sternum and the parietal (costal) part of the pleural membrane. As external intercostal muscles approach the ventral thoracic wall, they rapidly become less muscular and more aponeurotic in nature, and at distances 4 cm or more from the chondro-osseous union.
Slides 36
All the intercostal muscles have been removed showing internal thoracic artery and vein and parietal part of the pleural membrane.
Slides 37
Ventral abdominal aponeurosis overlying rectus abdominis.
Slides 38
Rectus abdominis.
Slides 39
External abdominis oblique courses down from the ribs medially to aponeurosis of the abdomen and rectus abdominis.
Slides 40
External abdominis oblique has been reflected to reveal internal abdominal oblique.
Slides 41
External and internal abdominis oblique have been reflected revealing transversus abdominis.
Slides 42
Window in abdominal musculature reveals the courses of external, internal, and transverse abdominis.
Slides 43
Close-up of window in abdominal musculature reveals the courses of external, internal, and transverse abdominis.
Slide 44
Schematic drawing of the superficial muscles of the back on the right, the latissimus dorsi and trapezius have been removed to show the underlying levator, scapulae, rhomboideus, and serratius posterior inferior.

Slide 46
Trapeziusand latissimus dorsi, and the probe indicates the triangle of auscultation.
Slide 47
Trapezius and latissimus dorsi have been removed revealing rhomboideus major and minor and serratus posterior inferior.
