Transcript of 1. Eye – to see 2. Tympanic Membrane (Tympanum) – to hear 3. Hind Leg - jump 4. External Nare -...
1. Eye – to see
2. Tympanic Membrane (Tympanum) – to hear
3. Hind Leg - jump
4. External Nare - breath
5. Mouth - eat
6. Front Leg – movement
7. Nares - breath
8. Maxillary teeth – hold prey
9. Vomerine teeth – chew prey
10. Tongue – capture prey
Vomerine – chew the prey. Maxillary teeth hold the prey
Capture prey with their tongue. USE THEIR EYES to push food in their gullet.
EXTERNAL STRUCTURES OF THE FROG - DAY 1
11. Eustachian tube – equalize pressure
REVIEW:How does the frog eat?
• Look inside his mouth.• What are the two pads on the roof of his
mouth?• He uses his EYES to push the food down into
his gullet. (his tongue is connected in the front of his mouth – so he can’t use it to push down food like we do)
Internal Anatomy – DAY 2

DETERMINE GENDER – DAY 2
• IF YOU FIND BLACK AND WHITE SMALL BALLS INSIDE THE FROG – THESE ARE EGGS.– Congratulations you have a GIRL!!!!
IF YOU HAVE 2 SMALL KIDNEY BEAN SHAPED ORGANS LOCATED NEAR THE SPINE – congratulations you have a BOY!!!
LIFE CYCLE
• USE WHAT YOU KNOW TO FILL IN THE LIFE CYCLE DIAGRAM ON THE BACK OF YOUR DISSECTION PACKET.
INTERNAL ANATOMY – DAY 3DIGESTIVE SYSTEM
1 – GULLET2 – ESOPHAGUSFind the pancreas – located near the back of the
stomach, it looks like a think ribbon10 – STOMACHOpen up the stomach by cutting at the top and
bottom of it. Put your scissors inside the cut and it open to reveal what is inside
INTERNAL ANATOMY – DAY 3DIGESTIVE SYSTEM
12 – SMALL INTESTINEFind the connection where the small intestine and the
large intestine connect13 – LARGE INTESTINE – do not cut this…it contains
poop11 – MESENTERY – connective tissue that keeps all
internal organs together 14 – SPLEEN – draw in the spleen in the mesentery by
the small intestine – removes old blood cells
FILL IN THE DIAGRAM• Use the information you have gathered to fill in the diagrams
for the digestive system on your note packet.
EXCRETORY SYSTEM
• FIND THE KIDNEYS (maroon/red structures near the frog’s spine)
