ANAT 1053 Test 2 UPDATED ACTUAL
Exam Questions and CORRECT Answers
pre-ganglionic neuron - CORRECT ANSWER - Cell body in CNS. From CNS to ganglion
post ganglionic neuron - CORRECT ANSWER - Cell body outside CNS. From ganglion to
effector organ
Sympathetic Nervous System (SNS) - CORRECT ANSWER - the division of the autonomic
nervous system that arouses the body, mobilizing its energy in stressful situations
parasympathetic nervous system - CORRECT ANSWER - the division of the autonomic
nervous system that calms the body, conserving its energy
SNS (sympathetic nervous system) organs - CORRECT ANSWER - eyes, heart, lungs,
stomach and intestines, joints and skin.
parasympathetic nervous system organs - CORRECT ANSWER - lungs, heart, bladder, and
stomach
Spirometry graph - CORRECT ANSWER - charts that plot the volume and flow of air coming
in and out of the lungs from one inhalation and on exhalation
atmospheric pressure - CORRECT ANSWER - the pressure caused by the weight of the
atmosphere
intrapleural pressure - CORRECT ANSWER - pressure in the pleural cavity surrounding the
lungs
, intra-alveolar pressure - CORRECT ANSWER - pressure of air in alveoli, always equalizes
with atmospheric pressure
External respiration reaction mechanism - CORRECT ANSWER - - oxygen is loaded into
blood
- alveoli always have more O2 than blood
-oxygen moves by diffusion towards the area of lower concentration
- pulmonary capillary blood gains oxygen
- carbon dioxide is unloaded out of the blood
- blood leaving lungs has oxygen and no carbon
internal respiration reaction mechanism - CORRECT ANSWER - - exchange of gasses
between blood and body cells
- opposite reaction to what occurs in the lungs
- carbon dioxide diffuses out of tissue to blood called loading
- oxygen diffuses from blood into tissue called unloading
Inspirations reserve volume - CORRECT ANSWER - amount of air that can be drawn into the
lungs beyond normal quiet inspiration (3,100ml)
Expiration reserve volume - CORRECT ANSWER - Amount of air that can be expelled
beyond the normal quiet expiration (1,200ml)
chronic obstructive pulmonary disease (COPD) - CORRECT ANSWER - permanent,
destructive pulmonary disorder that is a combination of chronic bronchitis and emphysema
PTH (parathyroid hormone) - CORRECT ANSWER - A peptide hormone that increases
blood calcium concentrations.
Calcitonin mechanism - CORRECT ANSWER - Inhibit osteoclast activity
