Nerve cells that transfer info w/in the body
Three types of neurons
Sensory: transfer info from body to CNS
Interneuron: connect sensory & motor neurons
Motor Neurons: transfer info from CNS to body
Which nervous system includes the brain and spinal cord?
Central Nervous System
Cephalization is apparent in what?
The first thing sound waves encounter?
Tympanic membrane (eardrum)
Where is the tympanic membrane located?
End of the ear canal
What causes dizziness?
Fluid around the semicircular canal
Main body part related to balance?
Rods & cones
Light & dark sensory transduction in the retina
Senses, motor skills, reasoning, language
Types of bee dances
Round: says food is near
Waggle: tells distance & direction of food
thin protein filaments, troponin/tropomyosin
Thick protein filaments, myosin heads
Action potential goes to the ____ and travels through ____ to ____ ____. Releasing ____ to ____ ____ to diffuse to the ____ of the ____/____ ____. When ____ lands on the Troponin it shifts the ____/____ ____ to reveal ____ ____ on the ____. This triggers ____ ____ to create a ____ ____ to ____. The ____ is pulled towards the _-____ making muscle fibers ____. This is called a ____ and requires ____ to fuel itself.
Action potential goes to the (sarcolemma) and travels through (T-tubules) to (terminal cisternae). Releasing (Ca+) to (sarcoplasmic reticulum) to diffuse to the (Troponin) of the (troponin/tropomyosin complex). When (Ca+) lands on the Troponin it shifts the (troponin/tropomyosin complex) to reveal (active sites) on the (actin). This triggers (myosin heads) to create a (cross bridge) to (actin). The (actin) is pulled towards the (M-line) making muscle fibers (shorten). This is called a (contraction) and requires (ATP) to fuel itself.
Basic contractile units of skeletal muscles
Define motor unit
Single neuron and all it controls
_______ muscle has intercalated discs.
_______ muscle lacks striations.
_______ muscle is striated, voluntary, fast & slow twitch
How does a hydrostatic skeleton work & 2 phyla associated with it?
Fluid under pressure in closed compartments that change shape by muscle contraction
& flatworms and nematodes
The sum of actions
Fixed Action Pattern = unlearned acts linked to simple stimulus (reflexes)
Cnidarian clock =
Cnidarian rhythm =
Cnidarian clock = internal 24hr activity cycle
Cnidarian rhythm = external annual cycle
Define pheromones & give 3 examples of the result of pheromones
molecules that convey reproductive behavior
Ex: alarm signal, courtship, social order
Innate vs learned behavior
Innate = developmentally fixed
Learned = modified based on experience
What occurs in spatial learning?
Establishment of memory that reflects environments spatial structure
(Result = walking in the dark)
Define foraging behavior
Food obtaining behavior
Define these mating systems:
Promiscuity = no strong pair bonds
Monogamy = one male w/one female
Polygamy = one individual w/several others
Polygyny = one male w/many females
Polyandry = one female w/many males
Intersexual ca intersexual selection
Inter = based on a characteristic (song or dance)
Ingram = based on competition
Sympathetic vs parasympathetic nervous systems
Sympathetic = release adrenaline (raises hr)
Parasympathetic = promotes calming and returning to normal (lowers hr)
Brainstem = transfers info btwn PNS, midbrain, & forebrain
Cerebrum = skeletal muscle contraction
Cerebellum = mvmt & balance
Thalamus = transfers sensory info to cerebrum
Hypothalamus =thermostat & clock
Frontal lobe =
Temporal lobe =
Parietal lobe =
Occipital lobe =
Frontal lobe = skeletal muscle & decision making/planning
Temporal lobe = hearing & language
Parietal lobe = touch & sensory
Occipital lobe = object/pattern recognition
Define and give example:
Electromagnetic receptor =
Pain receptor =
Mechano = deformation/shapes change Ex: whiskers
Chemo = total solute concentration & individual molecules Ex: taste buds
Electromagnetic receptor = elect. energy Ex: magnetite
Thermoreceptor = heat & cold
Grains in the ear that give gravitational orientation are called...
Smell & taste receptors
