Flashcards in anthropoda Deck (35):
1

The appendage is very stable and requires little brain power to move

jointed appendage/leg

2

The phylum containing

grasshoppers.

anthropoda

3

Entry point into tracheal Tube system.

spiracle

4

the grasshopper crushing jaw

is a mandible

5

fusion of head and thorax

cephalothorax

6

from insectus, meaning "cut into sections"

insecta

7

Excretry structures in a
grasshopper.

malphigian tubules

8

‘Front lip’ of a grasshopper.

labrum

9

an 'outer' skeleton

exoskeleton

10

has lobster and shrimp

crustacea

11

secretes digestive enzymes into the stomach

gastric caeca

12

what is maxilla

help to move food into the mouth

13

section contains the major organs in the insect

abdomen

14

animals in this class really have less than 100 legs

Chilopoda

15

the 'blood cavity' containing the major organs

haemocoel

16

the rear lip of a grasshopper

what is a labium

17

shedding of an exoskeleton to allow growth

molting

18

posses pedipalps and chelicera

arachnida

19

structure moving oxygen to the cells of a grasshopper

tracheal tube network

20

the grasshopper mouthparts containing sensory palps

maxilla and labium

21

Anthropoda

anthro=joint, pada=foot

22

anthropoda key features

1. exoskeleton (outer, skeletone)
-composed of chitin and proven
-strong/waterproof
2. Segmented body plan
-development of special appendages with joint
parts
4.Jointed legs and appendages
5.high degree of cephalization

23

anthropoda divided into distinct parts

-head: mouth and sense organs
-thorax: walking legs, wings, and part of digestive system, compound eye
-Abdomen: Major internal organs, reproductive organs
-Cephlothorax: head and thorax

24

arthropoda can

transition to land
-appendages, development of wings
-metamorphosis:
-transition between body forms
Symbiotic relationships
-decomposers
-breakdown of dead organisms

25

arthropoda muscular system

1. Muscular-complex system
a) Muscles occur in bundles & attached to inside of exoskeleton
2. Reduced Coelom; most of the body cavity consisting of hemocoel filled with blood

26

arthropoda circulatory system

-open system
-blood is pumped by a heart (dorsal vessel) into a hemocoel (cavity) blood delivers nutrients + picks up waste directly from organs
-valve in dorsal vessel prevents backflow

27

Excretory System

-Malphigian tubules: drain metabolic waste from body fluids into intestine

28

Respiratory system

-aquatic: use gills
-terrestrial: tracheal system
-branching network of hollow tubes delivers oxygen to organs

29

Nervous system

-two ventral nerve cords
-dorsal brain
-well developed sense organs

30

metamorphosis

-complete 4 stages (egg,larva, pupa, adult)
-gradual: eggs hatch into miniature version of adults
-molting: shedding skeleton when growing and developing

31

Insecta class

-bees/ants: hierarchal order
-pheromones: affect the development and behaviour of colony
-mouthparts specialized for
-piercing and sucking (mosquito)
-biting and chewing (grasshopper)
-siphoning (Butterly)
-sponging (some flies)

32

Arachnida class

-two body regions: abdomen,, cephalothorax
-8 legs
-major organs in abdomen
-book lungs: gas exchange

33

Crustacea class

-cephalothorax
-two pairs of antennae
-gills used for gas exchange
-5 or more pairs of legs first pair are pincers

34

Chilopoda class

centipedes
-ventrally flattened
-one pair of legs per segment
-carnivores with poison fangs

35

Diplopoda class

-millipedes
-two pairs of legs per segment
-herbivores
