Internal (WIP) Anatomy & Physiology Flashcards
Hemolymph
Insect blood
Green or yellow color
Hemocel
Body cavity
Hemocytes
Blood cells circulating in the hemolymph
Name three hemolymph functions
(Insect blood)
- Transports: Nutrients, waste, hormones.
- Immune Function: Cells for healing
- Pressure source: Hydraulic during molting
What type of circulatory system do insects have?
Open circulatory system
Where’s the heart located?
Dorsal heart
Phytophagous
Herbivorous
Zoophagous
Carnivorous
Saprophagous
Decomposers
Sensory Systems
Photoreceptors
Sense light, day length, light intensity, color
Chemoreceptors
Detect general odorants,
tastants, or pheromones
Common on: Mouthparts, Antennae, Tarsi
Mechanoreceptors
- Sensitive to touch, vibration, or have spatial sensitivity
Most abundant sensory organs:
Dome-like (campaniform)
Hair-like (trichoid)
Plate-like (placoid)
Mechanoreceptors
Geomagnetic receptors
In honey bees, ants and monarch butterflies for orientation and navigation
Sense magnetic fields
Mechanoreceptors
Hygroreceptors
Perceiving moisture in the air
Parthenogenetic
Asexual reproduction
Reproduction Methods
Oviparity
Egg laying
Reproduction Methods
Ovoviviparity
Egg remains in body until it hatches
Reproduction Methods
Viviparity
Egg hatch occurs inside mother, is “born.”
Spermatheca
Receives and stores sperm in the female.
Musculature
Appendage muscle
Move segments of the appendage
Musculature
Visceral
- Found around digestive tract
- Peristaltic movements of gut - move food and waste along
- Peristalsis of the heart – move hemolymph forward
Musculature
Segmental
Series of bands connecting body segments
Spiracles
“Holes” in the insect that allow them to breath.
Connects to tracheal tube
Is the trachea lined with the cuticle?
Yes
