Formal Assessment #4 Zoo02 Summer Classes
The student is expected to apply the information given on the introduction to the skeleton and the comparative anatomy of the appendicular skeleton through their ability to recall facts, differentiate terms and apply what they have learned through out the lesson.
- 1.
The humerus is a propodium.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The humerus is indeed a propodium. The term "propodium" refers to the forelimb or the anterior limb of a vertebrate. In the case of humans and other mammals, the humerus is the bone that forms the upper arm and connects the shoulder to the elbow. Therefore, it can be concluded that the statement is true.Rate this question:

Digits III and IV support the artiodactyls’ weight.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Artiodactyls are a group of mammals that have an even number of toes on their feet. The digits III and IV refer to the third and fourth toes of the artiodactyls. These toes are responsible for supporting the weight of the artiodactyls. Therefore, the statement that digits III and IV support the artiodactyls' weight is true.Rate this question:

The radius is an autopodium.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "The radius is an autopodium" is false. The radius is a bone in the forearm, specifically on the thumb side. An autopodium refers to the distal part of a limb, which includes the wrist and hand in humans. While the radius is part of the autopodium, it is not the autopodium itself.Rate this question:

The pelvic girdle of cetaceans is vestigial.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because cetaceans, which include whales, dolphins, and porpoises, have evolved from land-dwelling mammals to fully aquatic creatures. As a result, their pelvic girdle, which is the bony structure that connects the hind limbs to the spine, has become vestigial and serves no functional purpose. This adaptation allows for streamlined bodies and efficient swimming in water.Rate this question:

The tibia is an epipodium.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The tibia is indeed an epipodium. An epipodium is a structure found in some animals, such as certain mollusks and arthropods, which functions as a walking leg or support. In humans, the tibia is the larger of the two bones in the lower leg and is commonly referred to as the shinbone. It plays a crucial role in supporting body weight and providing stability during movement, making it comparable to an epipodium in its function. Therefore, the statement that the tibia is an epipodium is true.Rate this question:

The cleithrum is unique to birds.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The cleithrum is not unique to birds. It is a bone found in the pectoral girdle of many vertebrates, including fish, amphibians, and reptiles, as well as some birds. Therefore, the statement that the cleithrum is unique to birds is incorrect.Rate this question:

The epipodia of pinnipeds are adapted for swimming.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Pinnipeds are a group of marine mammals that include seals, sea lions, and walruses. While their epipodia, which are modified limbs, are adapted for swimming, the statement is incorrect. Pinnipeds have flippers instead of epipodia, which are specialized for efficient movement in water. These flippers have a streamlined shape and are used for propulsion and maneuverability while swimming. Therefore, the correct answer is false.Rate this question:
-
- 8.
The propodia and epipodia of birds decreases in length for flight.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because the propodia and epipodia of birds actually increase in length for flight. These structures, which are parts of the bird's wings, elongate during flight to provide more surface area for lift and maneuverability. This adaptation allows birds to generate the necessary lift and thrust for sustained flight.Rate this question:

Coracoid
- A.
Pectoral
- B.
Pelvic
- C.
Both
Correct Answer
A. PectoralExplanation
The correct answer is "Pectoral." The question is asking for the type of bone called "Coracoid" and the options given are "Pectoral," "Pelvic," and "Both." Based on the information provided, the bone "Coracoid" is classified as a "Pectoral" bone.Rate this question:

Carpometacarpus
- A.
Pectoral
- B.
Pelvic
- C.
Both
Correct Answer
A. PectoralExplanation
The correct answer is "Pectoral" because the term "Carpometacarpus" refers to a bone found in the wing of birds, specifically the fused bones between the wrist and the fingers. The pectoral region is associated with the chest and shoulders, which is where the wings are located in birds. Therefore, it is logical to conclude that the carpometacarpus bone is part of the pectoral region in birds.Rate this question:

Acetabulum
- A.
Pectoral
- B.
Pelvic
- C.
Both
Correct Answer
B. PelvicExplanation
The correct answer is "Pelvic." The term "acetabulum" refers to the socket in the hip bone where the head of the femur (thigh bone) fits in, and it is located in the pelvic region. Therefore, the answer "Pelvic" is the appropriate choice as it accurately describes the location of the acetabulum.Rate this question:

Attaches the fins and limbs to the axial skeleton
- A.
Pectoral
- B.
Pelvic
- C.
Both
Correct Answer
C. BothExplanation
The correct answer is "Both" because both the pectoral and pelvic girdles are responsible for attaching the fins and limbs to the axial skeleton. The pectoral girdle is located in the upper body and consists of the scapula and clavicle, which provide attachment points for the arms and shoulders. The pelvic girdle is located in the lower body and consists of the hip bones, which provide attachment points for the legs and hips. Therefore, both girdles play a crucial role in connecting the fins and limbs to the axial skeleton.Rate this question:

Furcula
- A.
Pectoral
- B.
Pelvic
- C.
Both
Correct Answer
A. PectoralExplanation
The term "furcula" refers to a bone found in birds, commonly known as the wishbone. The pectoral region, also known as the chest area, is where the furcula is located. On the other hand, the term "pelvic" refers to the region of the body associated with the pelvis or hip area. Therefore, the correct answer is "Pectoral" as it accurately identifies the region where the furcula is found.Rate this question:

Stabilizes posture and weight distribution for bipeds
- A.
Pectoral
- B.
Pelvic
- C.
Both
Correct Answer
B. PelvicExplanation
The correct answer is "Pelvic". The pelvic region of the body plays a crucial role in stabilizing posture and distributing weight for bipeds. The pelvis is a bony structure that connects the spine to the lower limbs, providing support and stability to the upper body. It helps in maintaining balance and preventing falls by acting as a foundation for the body's weight. Additionally, the pelvic muscles and ligaments also contribute to maintaining proper posture and distributing weight evenly, making the pelvic region essential for bipeds' stability.Rate this question:

Cleithrum
- A.
Pectoral
- B.
Pelvic
- C.
Both
Correct Answer
A. PectoralExplanation
The correct answer is "Pectoral" because the term "cleithrum" refers to a bone found in the pectoral girdle of fish. The pectoral girdle is responsible for connecting the fish's forelimbs or fins to its body. Therefore, the cleithrum bone is specifically associated with the pectoral girdle, making the answer "Pectoral" the correct choice.Rate this question:
-
- 17.
Clavicle
- A.
Pectoral
- B.
Pelvic
- C.
Both
Correct Answer
A. PectoralExplanation
The correct answer is "Pectoral." The clavicle is commonly known as the collarbone, and it is part of the pectoral girdle along with the scapula. The pectoral girdle connects the upper limb to the axial skeleton and provides support and mobility for the arm. The pelvis, on the other hand, is part of the pelvic girdle, which connects the lower limb to the axial skeleton. Therefore, the clavicle is not part of the pelvic girdle.Rate this question:
