Question 1

Which of the following muscles is NOT located in the neck?
A) sternomastoid
B) teres major
C) sternohyoid
D) digastric
E) mylohyoid

Accepted Answer

The teres major muscle is located in the upper arm, not in the neck. The sternomastoid, sternohyoid, digastric, and mylohyoid muscles are all located in the neck.

Question 2

A) levator scapulae ventralis
B) clavodeltoid
C) acromiotrapezius
D) latissimus dorsi
E) acromiodeltoid

Accepted Answer

The acromiodeltoid muscle originates on the acromion process of the scapula and inserts on the proximal end of the humerus. Its primary function is to flex the forelimb and rotate it laterally.

Question 3

Which group of muscles covers the ventral surface of the chest?
A) trapezius group
B) deltoid group
C) rhomboideus group
D) pectoralis group

Accepted Answer

The pectoralis group of muscles covers the ventral surface of the chest. The trapezius group covers the upper back, the deltoid group covers the shoulder, and the rhomboideus group covers the middle back.

Question 4

B) rhomboideus capitus
C) rhomboideus minor

Accepted Answer

The rhomboideus capitus is not found in humans.

Question 5

Which muscle of the neck functions to turn and depress the head?
A) sternomastoid
B) mylohyoid
C) digastric
D) sternohyoid

Accepted Answer

The sternomastoid muscle is responsible for turning and depressing the head. The mylohyoid muscle originates in the mandible and functions in elevating the hyoid bone and floor of the mouth. The digastric muscle is responsible for opening the mouth and depressing the mandible. The sternohyoid muscle is responsible for depressing the hyoid bone.

Question 6

Which muscle is located at the axillary border of the scapula?
A) splenius
B) supraspinatus
C) infraspinatus
D) rhomboideus major
E) teres major

Accepted Answer

The teres major muscle is located at the axillary (lateral) border of the scapula. It is involved in the medial rotation and adduction of the humerus.

Question 7

Cats have all of the same muscles as humans, and therefore they are an ideal specimen to study.
A) True
B) False

Accepted Answer

Cats and humans share many similarities in their muscular systems, making them suitable for comparative studies.

Question 8

Which group of muscles covers the dorsal surface of the neck and scapula?
A) trapezius group
B) deltoid group
C) rhomboideus group
D) pectoralis group

Accepted Answer

The trapezius group of muscles covers the dorsal surface of the neck and scapula. The rhomboideus group covers the medial border of the scapula, and the deltoid group covers the shoulder. The pectoralis group covers the anterior chest wall.

Question 9

Which muscle is a broad, flat, and thin muscle that covers most of the lateral surface of the cervical and thoracic vertebrae?
A) teres major
B) supraspinatus
C) infraspinatus
D) rhomboideus major
E) splenius

Accepted Answer

The muscle described is likely the splenius muscle, which is broad, flat, and thin, and covers much of the lateral surface of the cervical and thoracic vertebrae. The other muscles listed (teres major, supraspinatus, infraspinatus, and rhomboideus major) do not have this characteristic.

Question 10

In cats, the trapezius group of muscles is composed of three distinct muscles. How many muscle(s) make up the trapezius in humans?
A) two
B) one
C) three
D) four

Accepted Answer

In humans, the trapezius is a single, large, superficial muscle that extends longitudinally from the occipital bone to the lower thoracic vertebrae and laterally to the spine of the scapula.

Question 11

Which term refers to the tail end of a four-legged animal?
A) superior
B) caudal
C) inferior
D) cephalic

Accepted Answer

The term "caudal" refers to the tail end of a four-legged animal, as opposed to "cephalic" which refers to the head end. "Superior" and "inferior" refer to relative positions above or below a reference point, but are not specific to the tail end of an animal.

Question 12

How should the skin be separated from the underlying fascia?
A) use the pointed end of a pair of scissors to separate the skin from the underlying muscle and connective tissues
B) use the scalpel to separate the skin from the underlying muscle and connective tissues
C) use your fingers or a blunt probe to separate the skin from the underlying muscle and connective tissues

Accepted Answer

Using your fingers or a blunt probe is the best choice for separating the skin from the underlying fascia because it allows for a gentle and precise separation without damaging the underlying tissues. Using scissors or a scalpel may result in accidental cuts or tears in the fascia.

Question 13

Where should the first incision be made when dissecting a cat?
A) on the lateral side of the ventral surface near the neck
B) on the midline of the ventral surface just anterior to the tail
C) on the lateral side of the dorsal surface near the neck
D) on the midline of the dorsal surface just anterior to the tail

Accepted Answer

The first incision when dissecting a cat should be made on the midline of the ventral surface just anterior to the tail. This approach allows for a systematic exploration of the internal organs starting from the posterior end and proceeding anteriorly, minimizing damage to the structures being studied.

Question 14

Which letter is marking the teres major in this figure? 
A) A
B) B
C) C
D) D
E) E

Accepted Answer

The answer of Which letter is marking the teres major...

Question 15

Which term refers to the ventral surface of a four-legged animal?
A) inferior
B) superior
C) caudal
D) cephalic

Accepted Answer

The ventral surface is located on the underside or "belly" of the animal, which is the inferior aspect of the body.

Question 16

Which group of muscles comprises the shoulder muscles?
A) trapezius group
B) deltoid group
C) rhomboideus group
D) pectoralis group

Accepted Answer

The shoulder muscles comprise the deltoid group, which includes the anterior, medial and posterior heads of the deltoid muscle. Although the trapezius group, rhomboideus group, and pectoralis group are also located in the shoulder region, they do not comprise the entirety of the shoulder muscles.

Question 17

Which muscle is a large, flat muscle that lays posterior to the trapezius group?
A) deltoid group
B) levator scapulae ventralis
C) latissimus dorsi
D) supraspinatus

Accepted Answer

The latissimus dorsi is a large, flat muscle located on the posterior side of the body, behind the trapezius group. It is responsible for several movements of the arm, including extension, adduction, and medial rotation. The deltoid group, levator scapulae ventralis, and supraspinatus are all located in different areas of the body and are not directly behind the trapezius group.

Question 18

Which statement regarding the storage of your cat is most correct?
A) The cat should be stored in a sealed bag covered in distilled water.
B) The cat should be stored in a sealed bag with exposed muscles covered with paper towels that have been dampened with fixative.
C) The cat should be dried and stored in a sealed bag.
D) The cat should be stored on the dissecting pan without any coverings.

Accepted Answer

Option B is the correct answer because it describes the correct method for storing a dissected animal specimen. The muscles of the cat should be exposed and paper towels dampened with fixative should be placed on top for preservation. This ensures that the tissue does not dry out and that the specimen remains preserved for future use in dissection or study. Options A, C, and D are incorrect because they do not properly preserve the tissue or could lead to contamination or damage.

Question 19

To begin dissecting the cat, place it ________ side down on the dissecting tray.
A) dorsal
B) caudal
C) cephalic
D) ventral

Accepted Answer

The dorsal side of the cat is its back, and the ventral side is its belly. When dissecting a cat, it is placed ventral side down on the dissecting tray so that the internal organs can be accessed.

Question 20

Which of the following muscles is NOT found in humans?
A) levator scapulae ventralis
B) latissimus dorsi
C) trapezius
D) deltoid

Accepted Answer

The levator scapulae ventralis muscle is not found in humans.
