13 Axillary nerve. N. axillaris. Nerve that arises from the posterior cord (C5-6) and passes together with the posterior circumflex humeral artery through the axilla to the teres minor and deltoid muscles. D

14 Muscular branches. Rami musculares. Fibers to the teres minor and deltoid muscles. D

15 Superior lateral brachial cutaneous nerve. N.

cutaneus brachii lateralis superior. It supplies the area of the skin located somewhat over the deltoid muscle. D

16 THORACIC NERVES. Nn. thoracici. Twelve thoracic spinal nerves emerging below thoracic vertebrae 1-12, respectively. C

17 Posterior branches. Rami posteriores. Rami that pass dorsally through the autochthonous muscles ofthe back, then divide to form lateral and medial cutaneous branches. C

18 Lateral/medial muscular branches. Ramus muscularis lateralis/medialis. C

19 Posterior cutaneous branch. Ramus cutaneus posterior. C

20 Anterior branches (intercostal nerves). Rami anteriores (nn. intercostales). Rami forming the intercostal nerves ventrally in the thoracic region. C

21 Lateral cutaneous branch (pectoral/abdominal). Ramus cutaneus lateralis (pectoralis/ abdominalis). Nerve arising from the middle of the intercostal nerve. It passes obliquely ven-trad and appears between the slips of the serra-tus anterior muscle and the latissimus dorsi. C

22 Lateral mammary branches. Rami mammarii laterales. Rami of lateral cutaneous branches arising from T4-6 and passing anteriorly to the mammary region. C

23 Intercostobrachial nerves. Nn. intercostobr-achiales. Lateral cutaneous rami arising usually from T1, but also from T1-3 and passing to the upper arm. C

24 Anterior cutaneous branch (pectoral/abdominal). Ramus cutaneus anterior (pectoralis/ abdominalis). Branch that emerges medially and anteriorly and divides to form medial and lateral branches. C

25 Medial mammary branches. Rami mammarii mediales. Medial branches from the anterior cutaneous rami of intercostal nerves 2-4. C

26 Subcostal nerve. N. subcostalis. Anterior branch ofthe 12ththoracic nerve located below the 12th rib.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
