Figure 1. Ultrastructure of the carotid
body. (A) Reproduction of the original
drawing of Fernando de Castro
published in De Castro (1926), part of
the Fernando de Castro Archives.
Different glomeruli are shown close to
the carotid artery (A). Incoming
sympathetic nerve from the superior
cervical ganglion (E) is a minor
contribution to the innervation of the
carotid body. The same can be said
about the vagus nerve (LX) in the
vicinity of the carotid body. By contrast,
the most relevant contingent of
afferents comes from the intercarotid
(sinus) nerve branch of the
glossopharyngeal nerve (IX). A
sympathetic microganglion can be seen
within the latter nerve (cg). Adapted,

Figure 5. Relationship between arterial and microvascular Po2 and consequence upon
chemodischarge response curves. (A) Relationship between Pao2 and carotid body
microvascular (CBM) Po2. O2 pressure in inspired gas was lowered in steps. At each
step, Pao2, chemosensory nerve activity and phosphorescence images were
measured ca. 3 min after end‐tidal gas values stabilized. Average CBM Po2 was
calculated for central region of O2 pressure map of carotid body and this is plotted
against measured Pao2. Top: data from six cats are presented. Each cat has a
different symbol. Below: data from all six cats are fitted to single curve (line of identity
also shown). (B) Relationship between Po2 (arterial and CBM) and chemosensory
nerve activity. Measured values of chemosensory nerve activity in four different cats
are plotted against Pao2 (open circles) and CBM Po2 (filled circles). imp/s, impulses

To determine your rate of recovery, use the following formula:
Recovery heart rate = (exercise heart rate - recovery heart rate
after 1 minute) / 10
Recovery Rate Number
Condition
Less than 2 = Poor
2 to 2.9 = Fair
3 to 3.9 = Good
4 to 5.9 = Excellent
Above 6 = Outstanding
