Science quiz module 5 Flashcards
give an example of an invertebrate
starfish
describe different things about invertebrates
animals with no backbone, shells don’t cover the whole body, exoskeleton covers the whole body, very weak chitin, only radical symmetry.
give an example of a vertebrate
shark
describe different characteristics of (cartilage) vertebrates
animals with a backbone, much lighter/flexible, water animals only
give an example of a vertebrate (bone)
animals with a backbone, skeleton is less flexible, but more stronger, land animals.
——- is the precourser to bone
cartilage
describe long bones
thigh bone (femur)
describe short bones
fingers/toes
describe flat bones
skull
describe irregular bones
veretebrae
describe sesamoid bones
patella
describe skeletal muscles
used for motion, voluntary control, skeletal muscles have striations and nucleis on the side (moving your arm)
describe smooth muscles
used for organ movement, (intestines) involuntary control, no striatations and nucleis on the side (digestive system)
describe cardiac muscles
only found in the heart, involuntary coltron, intercalated disks branching central nucleis
describe tendons
connect muscle to bone, flexible, connection between bones and muscle
describe ligaments
fibrous tissues, connects bone to bone, connection between bones
what is the sarcomere
the funtional unit of muscle tissue is the sacromere, an action/reaction, requires a nerce and calcium
how can you tell when muscles are relaxed or stressed
the H zone, or the middle is closer together for stressed
where is the sacromere on the muscle
the dotty stuff on the sides
describes the veins
blood toward, the biggest have valves, carries blood toward the heart
describe arteries
carries blood away from the heart, 2nd biggest, dub on side of the heart
describe capillaries
O2Ca gas exchange, diffusion, no muscle
what is the heart evolution for fish
1st, 2 chambers exo
the heart evolution for amphibians
3 chambers, 2nd exo
the evolution for reptiles
3rd, exo, 4 chambered, heart with septal defect
the heart evolution for birds
4th, endo, 4 chambered aorta to the right
the heart evolution for mammals
5th, endo, four chambered aorta left
function of the amygdala
fear
function of the corpus callosum
connects left and right sides
function of the hypothalamus
makes hormones and regulates homostasis
function of the ventricles
cussion and support
function of the cingulate gyrus
motion
describe white matter
faster, myleim, body
describe gray matter
in brain, slower
what causes a stroke
broken/clogged blood vessels, oxygen blooked to brain
Dr Jill Botle - Taylor
studied things about the stroke while having one
evolution of the brain, different animals
fish - compartments
amphibians - logic
reptiles - segmentation
birds - lobes/problem solving
