Mechanoreceptors

A
  • Sensitive to touch, vibration, or have spatial sensitivity
    Most abundant sensory organs:
    Dome-like (campaniform)
    Hair-like (trichoid)

Q

Reproduction Methods

Oviparity

A

Egg laying

16
Q

Reproduction Methods

Ovoviviparity

A

Egg remains in body until it hatches

17
Q

Reproduction Methods

Viviparity

A

Egg hatch occurs inside mother, is “born.”

18
Q

Spermatheca

A

Receives and stores sperm in the female.

19
Q

Musculature

Appendage muscle

A

Move segments of the appendage

20
Q

Musculature

Visceral

A
  • Found around digestive tract
  • Peristaltic movements of gut - move food and waste along
  • Peristalsis of the heart – move hemolymph forward
21
Q

Musculature

Segmental

A

Series of bands connecting body segments

22
Q

Spiracles

A

“Holes” in the insect that allow them to breath.

Connects to tracheal tube

23
Q

Is the trachea lined with the cuticle?

A

Yes

24
Q

What does the trachea

It is connected to the spiricles

A

Diffusion of oxygen, removal of CO2 through spiracles

25
Q

is the foregut and hindgut lined with the cuticle? Why?

A

Yes. Protects the digestive system from tough things the bug might have ate like rocks.
