Chapter 8 discusses anatomical considerations related to arteries and veins, outlining anatomical positions, guides, and limits. It details key arteries such as the common carotid, axillary, brachial, radial, and ulnar, along with their origins, branches, and relationships to surrounding veins. Additionally, the chapter covers major arteries of the body trunk, including the aorta and its branches.

2. Anatomical Position
• The subject is standing erect,
the arms of the subject are at
the sides with the palms of
the hands facing the
observer, the feet are
together, and the subject is
facing the observer.

linear guide for the veins would
be the opposite of those of the
respective arteries.

would be the same.
