What muscle of the human is homologous to the Sternomastoid muscle of the cat?

What muscle of the human is homologous to the Sternomastoid muscle of the cat?

The 2. The 3. Two muscles of the cat that are inserted on the hyoid bone are the muscle of the human is homologous to the sternomastoid muscle of the cat. A3 muscle elevates the mandible in the human and in the cat.

How does the human biceps brachii muscle differ from the cats?

How does the biceps brachii differ between cats and humans? The human biceps brachii includes two heads of origin, from which its name is devried: a short head at the glenoid fossa and a long head at the coracoid process. The biceps brachii of the cat has only one origin: the glenoid fossa.

Which cat muscle does not correspond to a human muscle?

b. Circle the muscle that does not correspond to a human mascle: biceps brachi, brachialis, xiphihumeralis latissimus dorsi. How does the deltoid of the cat differ from the deltoid of the human?

What muscle elevates the mandible in the human and in the cat?

The function of the masseter muscle is to elevate the mandible and approximate the teeth—additionally, the intermediate and deep muscle fibers of the masseter function to retract the mandible. And the superficial fibers function to protrude the mandible.

What are the muscles of the cat?

The two main integumentary muscles of a cat are the platysma and the cutaneous maximus. The cutaneous maximus covers the dorsal region of the cat and allows it to shake its skin. The platysma covers the neck and allows the cat to stretch the skin over the pectoralis major and deltoid muscles.

What four muscles make up the quadriceps of cat?

It has four parts: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius.

Where is the Sartorius muscle found in the cat?

The most anterior muscle of the cat thigh is the sartorius. This muscle appears as a wide, thin band extending from its origin on the ilium to its insertion on the patella and tibia. The majority of the muscle rests on the medial side of the thigh, covering nearly half of its anterior surface.

Does the biceps have two heads in the cat?

hamstring muscles, biceps femoris, and semitendinosus were examined in adult cats using microdissection and glycogen-depletion techniques. The biceps femoris muscle consists of two heads. The anterior head, which attaches mainly to the femur, is divided into two parts by the extramuscular branches of its nerve.

What muscles flex the hand group of answer choices?

The muscles that flex the hand at the wrist include the flexor carpi radialis, flexor carpi ulnaris and the palmaris longus.

What muscle elevates the mandible in the human and pig?

Where is the masseter located and what is its purpose? It is located ventral and lateral to the mandible. This muscle elevates and protrudes the mandible, facilitating chewing or grinding food.

Which muscle opens the jaws and protrudes the mandible?

masseter muscle
The masseter muscle provides powerful elevation and protrusion of the mandible by originating from the zygomatic arch and inserting along the angle and lateral surface of the mandible. The temporalis muscle originates from the floor of the temporal fossa and inserts onto the coronoid process of the mandible.

How are cats so flexible?

A cat’s spine can rotate more than the spines of most other animals, and their vertebrae have a special, flexible, elastic cushioning on the disks, which gives it even more flexibility. A flexible spine also contributes to the speed and grace of cats.

What is the function of the forelimb joints and musculature?

The role of the forelimb joints and musculature as determined by inverse dynamics analysis will be described later in this chapter. In small, non-cursorial mammals, the forelimb is attached to the trunk via a shoulder girdle, in which the clavicle articulates with the sternum and scapula, imposing some constraints on forelimb motion.

What is the function of the intrinsic muscles in a horse?

Intrinsic muscles of the forelimb. In the walking horse, the shoulder acts primarily as an energy damper, with a large burst of energy absorption on its extensor (cranial) aspect in midstance ( Clayton et al., 2000a ), which is likely due to eccentric action of biceps brachii controlling extension of the shoulder.

What part of a horse’s body does locomotor muscle make up?

Locomotor muscles account for about 42% of the horse’s body mass (Gunn, 1978) with the large, powerful muscles concentrated in the proximal limb, while the distal forelimb makes use of long, elastic tendons to reduce the metabolic cost of locomotion. The bulk of the musculature is in the proximal limb,…

What is the function of the forelimb in a horse?

Forelimb function. Terminology. This chapter reviews the structure and functions of the equine forelimbs in relation to locomotor activity, including kinematics (movements) and kinetics (forces) during the stride. A stride is regarded as the unit of measurement.
