Week 11 Flashcards
Mechanoreceptors
Respond to mechanical force
Chemoreceptors
Respond to specific chemicals
Electromagnetic receptors
Respond to electromagnetic energy and magnetic fields
Thermoreceptors
Respond to temperature
Pain receptors
Respond to damaged tissue
What receptors can be found in your skin
Mechanoreceptors, thermoreceptors, pain receptors
Lateral line system
Series of small openings in a side of a fish (kind of mechanoreceptor)
5 types of chemoreceptors in your mouth
Sweet, sour, salty, bitter and umami receptors
Retina is where you have the
Actual photo receptors
Choroid
Blocks light and feeds the retina
Sclera
Protects the eye and gives it shape
Cornea
Starts the process of focusing light
Aqueous humour
Constantly replaced, feeds the cornea and the lens
Iris
Controls the amounts of light that gets in your pupil (pigmented colour of your eye)
Pupil
Hole in the iris
Lens
Adjusts the focus
Rod
Responds to a wide range of colours, black and white vision, very sensitive, 125 million rods
Cone
Three kinds, respond to green, red or blue light, colour vision, relatively insensitive, 6 million cones
Optic nerve
No photoreceptors
Ecology
The study of how organisms interact with their environment, understand the distribution and abundance of organisms, the focus of study is different
Organism
Individual living system
Population
Group of organisms of the same species living in an area
Community
A group of populations in an area
Ecosystem
A community plus the non living environment in which it lives
Landscape
A mosaic of connected ecosystems
Biosphere
The sum of all the planets landscapes
Organismal ecology
Including evolutionary ecology and behavioural ecology, focuses on how an organisms anatomy, physiology and behaviour meet the challenges imposed by its environment
Population ecology
Focuses on the factors that influence population size
Community ecology
Focuses on how interactions between species influence community structure
Ecosystem ecology
Focuses on energy flow and nutrient cycling
Landscape ecology
Focuses on exchange of energy, materials and organisms among ecosystems
Global ecology
Focuses on the distribution and function of ecosystems across the biosphere
Behavioral ecology
The study of the ecological and evolutionary basis for animal behaviour
