Weeks 6-11
- Week 6
- Thorax
Anatomy
- skeletal
components
- thoracic vertebrae
- ribs and their costal cartilages
- sternum
- thoracic vertebrae
- muscular components
- intercostal muscles
- intercostal muscles
- neurovascular components
- intercostal nerves
- intercostal arteries and veins
- intercostal nerves
- thoracic inlet - T1 vertebra, superior border of manubrium,
medial border of the first rib its costal cartilage
- thoracic outlet - inferior diaphragm surface
- repiration muscles
- diaphragm
- intercostal muscles -
external, internal, innermost
- diaphragm
- pleura
- parietal - cervical, costal, media-stinal, diaphragmatic
- visceral
- parietal - cervical, costal, media-stinal, diaphragmatic
- lungs
- right - sup, inf, mid
- left - sup, inf
- right - sup, inf, mid
- mediastinum - superior, inferior - middle, anterior
- heart - endo, myo, epi - cardium
- skeletal
components
- The Heart
- Flow of Blood through the chamber
of the heart and vessel names
- order of excitation
- ionic basis of APs in the SA node and ventricle
- What the ECG represents
- names/durations of ECG waves
- what the ECG waves and intervals reflect
- different phases of the cardiac cycle
and how these relate to the ECG
- CO = HR x SV
- autonomic stimulation on HR and SV
- regulation of SV
- calculating MAP and regulation of arterial BP
- CO = MAP/TPR
- sympathetic stimuation on vessel diameter
- active hyperaemia and control regional blood flow
- location and role of arterial baroreceptors
- Flow of Blood through the chamber
of the heart and vessel names
- Gas Exchange
and Transport
- O2 and CO2 diffuse down
their concentration gradients
- CO2 is about 20X more soluble than O2
- O2 transported in the blood by haemaglobin
- Unloading of O2 encouraged by low pH
high temp, high 2,3,BPG and high CO2
- CO2 transported in the blood as bicarb
- O2 and CO2 diffuse down
their concentration gradients
- Responses to
Exercise
- both central and peripheral mechanisms contribute to
cardiovascular and respiratory responses during exercise
- central command is responsible for the initial increase in heart rate
- the muscle chemoreflex contributes to the slower, sympathetically-mediated
rises in heart rate, stroke volume and peripheral vasoconstriction
- endurance training results in alterations in cardiac structure/size, angiogenesis
and increases mitochondria number and myoglobin concentration
- these alterations increase stroke volume and VO2
- both central and peripheral mechanisms contribute to
cardiovascular and respiratory responses during exercise
