1.23.1.15 - ANS and the CRS
neurotransmitters and receptors
sympathetic
pre ganglionic
neurotransmitter-acetylcholine
cholinergic nicotinic Ach R receptors
post ganglionic
adrenergic α and/or β receptors
neurotransmitter- noradrenaline
parasympathetic
pre ganglionic
neurotransmitter- acetylcholine
cholinergic nicotinic Ach R receptors
post ganglionic
neurotransmitter- acetylcholine
cholinergic muscarinic Ach R receptors
autonomic reflexes
neural regulation of the ANS is by reflexes
sympathetic effect on lungs and heart
lungs
circulating adrenaline
dilates bronchioles
heart
releases hormones- adrenaline and noradrenaline
accelerate the heart rate
increases force of contraction
Pre-ganglionic fibres are short in length. Post-G fibres are long in length
receptors
baroreceptors
regulation of homeostasis
located in the carotid sinus and the aortic arch
sensing pressure changes
changing tension in the arterial wall
chemoreceptors
sensitive to changed in blood molecule concentrations
oxygen or carbon dixoide
involved in homeostasis
under ventral surface of the medulla and in the carotid and aortic bodies
