14 White matter. Substantia alba. Consists of myelinated nerves and is organized into three cords (funiculi) which contain the nerve pathways. A

15 Substantia gelatinosa centralis. A narrow zone around the central canal with processes from ependymal cells.

16 GRAY COLUMNS. Columnae griseae. Three ridge-like columns of gray matter. B

17 Anterior column. Columna anterior. It is comprised predominantly of motor neurons (anterior horn cells). B

18 Anterior horn. Cornu anterius. Hook-shaped structure seen in transverse section of the spinal cord. D

19 Anterolateral nucleus. Nucleus anterolater-alis. Situated anterolaterally in the anterior horn, it is localized in segments C4-8 and L2-S1 and innervates the muscles of the limbs. D

20 Anteromedial nucleus. Nucleus anterome-dialis. From its anteromedial position in the anterior horn, it extends the entire length of the spinal cord.D

21 Posterolateral nucleus. Nucleus posterolater-alis. It lies posterior to the anterolateral nucleus in segments C5-T1 and L2-S2 and innervates the muscles of the limbs. D

22 Retroposterolateral nucleus. Nucleus retro-posterolateralis. It lies posterior to the post-erolateral nucleus in segments C8-T1 and S1-3. D

23 Posteromedial nucleus. Nucleus posterome-dialis. From the vicinity of the white matter, it extends over segments T1-L3 and probably innervates the trunk musculature. D

24 Central nucleus. Nucleus centralis. A less prominent group in several cervical and lumbar segments. D

25 Nucleus of accessory nerve. Nucleus nervi ac-cessorii (nuc. accessorius). It lies in segments C1-6 in the area of the anterolateral nucleus and provides the root fibers of the spinal portion of the accessory nerve. D

26 Nucleus of phrenic nerve. Nucleus nervi phrenici (nuc. phrenicus). It lies in the middle of the anterior horn and extends from segments C4-C7. 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.
