1 Isthmus of auricular cartilage. Isthmus car-tilaginis auricularis. Narrow bridge of cartilage connecting the cartilage of the external acoustic meatus and tragic lamina with the auricular cartilage. A

2 Terminal notch. Incisura terminalis auricularis. Deep notch separating the lamina tragi from the auricular cartilage. A

3 Fissura antitragohelicina. Deep fissure separating the antitragus and helix inferiorly as well as the anthelix and helix further superiorly. A

4 Transverse sulcus of anthelix. [[Sulcus antheli-cis transversus]]. Posteromedial depression visible between the eminences of the triangular fossa and concha. A

5 Groove of crus of helix. Sulcus cruris helicis. Shallow furrow on the posterior surface of the auricular cartilage. It corresponds to the crus of the helix on the anterior surface. A

6 Fossa of anthelix. Fossa anthelicis. Furrow on posterior surface of auricular cartilage corresponding to the anthelix on the anterior surface. A

7 Eminence of concha. Eminentia conchae. Elevation on the posterior surface of the auricular cartilage corresponding to the cavity of the concha. A

8 Eminence of scaphoid fossa. Eminentia scaphae. Curved elevation on the posterior surface of the auricular cartilage corresponding to the scaphoid fossa on the anterior surface. A

9 Eminence of triangular fossa. Eminentia fossae triangularis. Elevation on the posterior surface of the auricular cartilage corresponding to the triangular fossa. A

10 Auricular ligaments. Ligg. auricularia. Ligaments of the pinna. They attach the auricular cartilage to the temporal bone.

11 Anterior auricular ligament. Lig. auriculare an-terius. It extends from the root of the zygomatic arch to the spine of the helix. B

12 Superior auricular ligament. Lig. auriculare su-perius. It passes from the upper margin of the osseous external auditory meatus to the spine of the helix. B

13 Posterior auricular ligament. Lig. auriculare posterius. It extends from the eminence of the concha to the mastoid process. C

14 Mm. auriculares. Muscles of the pinna.

15 M. helicis major. It passes upward from the spine of the helix to the helix. B

16 M. helicis minor. It lies on the crus of the helix. B

17 M. tragicus. It lies vertically on the lamina tragi. B

18 M. pyramidalis auricularis. Muscle fibers that occasionally split off from the tragicus muscle and pass to the spine of the helix. B

19 M. antitragicus. Muscle fibers on the anti-tragus. They extend partly to the tail of the helix. B

20 M. transversus auricularis. Muscle located on the posterior surface of the auricular cartilage. It extends between the eminences of the scaphoid fossa and concha. C

21 M. obliquus auricularis. It lies between the eminences of the concha and triangular fossa. C

22 [M. incisurae helicis]. Muscle fibers occasionally present in the caudal continuation of trans-versus auricularis muscle. C

23 olfactory organ. Organum olfactorium (ol-factus). Organ of smell.

24 Nasal mucosa of the olfactory region. Regio olfactoria tunicae mucosae nasi. This region, which is covered by olfactory epithelium, is about the size of a nickel and occupies the lateral and medial walls and roof(belowthe cribriform plate) of the nasal cavity at the level of the superior nasal concha. E F

25 Olfactory glands (of Bowman). Glandulae ol-factoriae. Serous glands found below the olfactory epithelium. Their predominantly serous secretions can enhance or wash away odorous substances. F

26 gustatory organ. Organum gustatorium (Gustus). Organ of taste, comprised of all the taste buds.

27 Taste bud. Caliculus gustatorius (gemma gusta-toria). Occupying the full thickness of the epithelium, it consists of supporting cells and taste cells. Each of the taste cells has microvilli on its surface which serve as chemoreceptors. Distribution of taste buds: aggregated in the epithelium of vallate (circumvallate) and foliate papillae; solitary on the outside ofthe tongue. D

28 Taste pore. Porus gustatorius. Space left by the epithelium above the apex of the taste bud. Mi-crovilli project into it. D

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.
