what is a sensor
cell that transduce stimuli to signal
what detects stimuli in a sensor
membrane proteins
how to sensors respond to stimuli
altering action potential via flow ions
ion channels can open and close
how are sensors adapted
can ignore background information while allowing sensitivity to change
where does light action potential arrive at CNS
visual cortex
where does sound arrive at CNS
auditory
where does smell arrive at CNS
olfaction
what are some internal conditions that are monitored
body temperature
carbon dioxide levels
blood glucose
blood calcium
arterial pressure
oxygen levels
muscle tension
proprioception
what are exteroceptors
monitor external environment
what is the role of mechanoreceptors
supply information about shape, texture, weight of objects
mechanoreceptors allow animals to feel, maintain, balance and hear
how does mechanoreceptors allow animals to hear
sound waves becoming pressure in cochlear fluid
what is the role of chemoreceptors
detect carbon dioxide levels and create autonomic response
why are electroreceptors important in some fish
some have electrical organs that generate electric field, determining orientation and communication
how do thermoreceptors detect heat
specific nerve endings with specialized cells feel heat
what are the functions of enteroreceptors
monitor oxygen in blood
monitor blood pressure
monitor concentration solutes
what animals have proprioceptors
animals with well developed muscular system
what is the role of proprioceptors
monitor muscle activity e.g.
degree contraction
rate of change contraction
tension in tendons
what is echolocation
auditory mechanism using high frequency sound pulses to locate objects
what species use echolocation
toothed whales
micrichiropteran bats
cetaceans
shrew
asian cave swift
how are bats adapted for echolocation
snout covered in complex folds
large pinnae
