Hypothalamus
(Hi-poe-thal-ee-mus)
a region of the forebrain below the thalamus that coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity
Contractility
capacity for becoming shorter in response to a suitable stimulus
Hypercapnia
(Hi-per-cap-knee-e-ah)
excessive carbon dioxide in the blood
Hypoxaemia
(Hi-pox-ee-me-ah)
lower than normal oxygen tension (P O2) in the arterial blood, therefore lower than normal saturation of haemoglobin and oxygen content per unit volume
Acidosis
Abnormally high acidity of the blood and other body tissues
Haemoglobin
(He-mo-glow-bin)
the iron-containing protein with the property of binding oxygen, contained in red blood cells
Medulla
(Ma-doo-la)
The inner core of certain organs or body structures
Cerebral cortex
Brain region responsible for reasoning, mood, and perception
Reticular Activating System
the system of cells of the reticular formation of the medulla oblongata that receive collaterals from the ascending sensory pathways and project to higher centers; they control the overall degree of central nervous system activity
Vasomotor centre
A cluster of nerve cell bodies in the medulla oblongata that controls the diameter of blood vessels and regulates blood pressure
Intravascular
situated or occurring within a vessel or vessels of an animal or plant, esp. within a blood vessel or blood vascular system
Physiological parameter
(Fiz-ee-oh-logical per-am-eat-er)
Relating to normal healthful functioning of one of a set of measurable factors, such as temperature and pressure, that define a system and determine its behavior and are varied in an experiment
Hypovolaemia
(Hi-po-voe-leem-ee-ah)
A decreased amount of blood volume in the body
Amplitude
(Amp-lee-tood)
Largeness; extent; breadth or range
peripheral equality [of pulses]
Related to the outer boundary of regular pulses
palpable
to touch gently
renal function
proper operation of the kidneys
aortic stenosis
(Ay-ore-tick sten-oh-sis)
A narrowing of the aortic orifice of the heart or of the aorta near the valve
oximeter
(Oxy-meeter)
a photoelectric device that measures oxygen saturation of the blood by recording the amount of light transmitted or reflected by deoxygenated versus oxygenated hemoglobin
pons
that part of the central nervous system lying between the medulla oblongata and the midbrain, ventral to the cerebellum
