Lab 10 - Animal Anatomy And Physiology

Front 1

Tetrapod

Back 1

four-limbed vertebrates

Front 2

Axial skeleton

Back 2

consisting of skull, vertebral column, and rib cage

Front 3

Appendicular skeleton

Back 3

consisting of the pectoral and pelvic girdles and associated limbs

Front 4

Sensory capsules

Back 4

spaces for sensory organs in the skull

Front 5

Nasal capsule

Back 5

complex of nasal bones which house olfactory organs

Front 6

Otic capsules

Back 6

provide protection for the middle and inner ear

Front 7

Occipital Condyles

Back 7

allow the skull to pivot smoothly on the first vertebra

Front 8

Atlas

Back 8

first vertebra

Front 9

Axis

Back 9

second vertebra

Front 10

Secondary palate

Back 10

partition in higher tetrapods that divides the nasal passage from the oral cavity

Front 11

Maxilla

Back 11

upper jaw

Front 12

Mandible

Back 12

lower jaw

Front 13

Temporal fenestra

Back 13

holes in the temporal region of the skull which provide surface area for muscle attachment

Front 14

Function of vertebral column

Back 14

1) prodives a flexible protective covering for the spinal cord
2) supports the weight of the body's thoracic and abdominal cavities
3) provides surfaces for muscle attachment

Front 15

Neural arch

Back 15

space on dorsal surface of each vertebra where nerve cord passes

Front 16

Intervertebral discs

Back 16

allows articulation among centra and protect the bony surfaces from damaging each other

Front 17

5 categories of vertebrae

Back 17

1) cervical
2) thoracic
3) lumbar
4) sacral
5) caudal

Front 18

Pectoral girdle

Back 18

not directly attached to veretebral column;
scapula
humerus
ulna/radius
carpals
metacarpals
phalanges

Front 19

Pelvic girdle

Back 19

firmly fused to vertebral column which provides greater strength for propulsion;
pelvis
femur
tibia/fibula
tarsals
metatarsals
phalanges

Front 20

Posterior spine

Back 20

used for defense

Front 21

Thoracic legs

Back 21

5 pairs used for generating water currents and filter feeding

Front 22

Post-abdominal claw

Back 22

used to remove debris from under the carapace

Front 23

Brood pouch

Back 23

contains eggs which hatch inside the pouch and then emerge from the female

Front 24

parthenogenesis

Back 24

development of egg without fertlization by sperm

Front 25

Ectothermic

Back 25

heat comes from external sources

Front 26

Endothermic

Back 26

generate heat internally as a result of metabolism

Front 27

Homeothermic

Back 27

ability to thermoregulate

Front 28

Poikilothermic

Back 28

cannot thermoregulate; internal temperature fluctuates with environment

Front 29

Q10

Back 29

sensitivity of reaction to temperature;
= Rt/Rt-10
