Muscle Identification and Functions

The video tutorial provides a detailed examination of the neck muscles in cats, including the sterno mastoid, collido mastoid, mylohyoid, digastric, hypoglossus, masseter, sternohyoid, and sternothyroid muscles. It covers their origins, insertions, and functions, highlighting differences and similarities with human anatomy. The tutorial also includes practical tips for identifying these muscles during a dissection.

Which muscle originates from the manubrium of the sternum in cats?

• Collido Mastoid

• Masseter

• Sterno Mastoid

• Myelohyoid

What is the insertion point for both the sterno mastoid and collido mastoid muscles?

• Clavicle

• Mastoid process

• Hyoid bone

• Mandible

What happens when both the left and right sterno mastoid muscles contract simultaneously?

• The head remains still

• The head moves up

• The head moves down

• The head turns to one side

In humans, how are the sterno mastoid and collido mastoid muscles classified?

• As two separate muscles

• As part of the back muscles

• As one muscle

Where is the myelohyoid muscle located?

• On the neck

• On the cheek

• Under the chin

• On the forehead

Which muscle is found on either side of the myelohyoid?

• Masseter

• Digastric

• Collido Mastoid

• Sterno Mastoid

What is the primary function of the masseter muscle?

• Open the mouth

• Close the mouth

• Support the neck

• Move the head

Which muscle is considered extra credit and not included in the pinning quiz?

• Mastoid process

• Mandible

What can be seen if the sternohyoid is pushed to the side?

• Trachea and larynx

• Mastoid process

• Clavicle

• Mandible
