Fig. 12. — Connective tissues. A, Areolar (from beneath skin) ; B, adipose 

 (fat) ; C, reticular (from lymph node) ; D, fibrous (from longitudinal section of 

 a tendon) ; E, elastic (yellow) ; F, hyaline cartilage (from end of bone) ; G, 

 osseous (bone) cross section of Haversian system; H, blood corpuscles (human). 

 The red blood corpuscle is also known as an erythrocyte; the large mononuclear 

 leucocyte is known as a monocyte.
