Which of the following is not a primary muscle of mastication?

Please select an option Incorrect. The masseter muscles are jaw closing muscles and so are important in mastication. They are derived from the first visceral arch and are innervated by the mandibular branch of the trigeminal nerve. They originate from the maxillary region of the skull and zygomatic arch and insert on the caudal side of the mandible. WikiVet Article: Mastication Incorrect. The temporal muscles are jaw closing muscles and so are important in mastication. They are derived from the first visceral arch and are innervated by the mandibular branch of the trigeminal nerve. They originate from the lateral surface of the cranium and insert on the coronoid process. WikiVet Article: Mastication Incorrect. The lateral and medial pterygoid muscles are jaw closing muscles and so are important in mastication. They are derived from the first visceral arch and are innervated by the mandibular branch of the trigeminal nerve. The lateral pterygoid muscle originates from the pterygopalantine region of the skull and inserts on the lateral aspect of the mandible. The medial pterygoid muscle originates from the pterygopalantine region of the skull and inserts on the medial aspect of the mandible. WikiVet Article: Mastication Correct! The zygomaticus muscles purse the lips and are primarily muscles of facial expression. WikiVet Article: Mastication Incorrect. The digastricus muscles are jaw opening muscles and so are important in mastication. There are two muscle bellies; the cranial muscle belly is derived from the first visceral arch and is innervated by the mandibular branch of the trigeminal nerve and the caudal muscle belly is derived from the second visceral arch and is innervated by the facial nerve. They originate from the paracondylar process of the occipital bone and insert on the angle of the mandible. WikiVet Article: Mastication

Which tongue papillae are particularly well developed in the cat and give the tongue its rough texture?

Please select an option Incorrect. Vallate (or circumvallate) papillae are large papillae found in a row forming in inverted 'V' towards the base of the tongue, taste buds are found on the side of these papillae. They are no more developed in cats than in other species. The correct answer is filiform papillae. WikiVet Article: Tongue Incorrect. Foliate papillae are found on the caudal third of the tongue, either side of the midline and they are covered in taste buds. They are no more developed in cats than in other species. The correct answer is filiform papillae. WikiVet Article: Tongue Correct! Filiform papillae form backward-facing hooks which help hold food and in the cat they are very well developed to provide the abrasiveness needed for self-grooming. These papillae do not have taste buds. WikiVet Article: Tongue Incorrect. Conical papillae are found on the caudal third of the tongue interspersed between filiform papillae and they do not have taste buds. They are no more developed in cats than in other species. The correct answer is filiform papillae. WikiVet Article: Tongue Incorrect. Fungiform papillae are the red dots seen on the rostral two thirds of the tongue and they are covered in taste buds. They are no more developed in cats than in other species. The correct answer is filiform papillae. WikiVet Article: Tongue

Which two muscles shorten the oropharynx?

Please select an option Incorrect. The cricopharyngeal muscle constricts the propharynx and the stylopharyngeal muscle dilates the oropharynx. The pterygopharyngeal and palatopharyngeal muscles shorten the oropharynx. WikiVet Article: Oropharynx Correct! The pterygopharyngeal and palatopharyngeal muscles shorten the oropharynx. WikiVet Article: Oropharynx Incorrect. Although the palatopharyngeal muscle does shorten the oropharynx, the thyropharyngeal muscle constricts the propharynx. The additional muscle that shortens the oropharynx is the pterygopharyngeal muscle. WikiVet Article: Oropharynx Incorrect. The hyopharyngeal muscle constricts the propharynx and the cricopharyngeal muscle constricts the propharynx. The pterygopharyngeal and palatopharyngeal muscles shorten the oropharynx. WikiVet Article: Oropharynx Incorrect. Although the pterygopharyngeal muscle does shorten the oropharynx, the stylopharyngeal muscle dilates the oropharynx. The additional muscle which shortens the oropharynx is the palatopharyngeal muscle. WikiVet Article: Oropharynx

Which laryngeal muscle is the principle abductor of the arytenoids?

Please select an option Incorrect. The cricothyroid muscle moves cricoid and arytenoid cartilages caudally thereby tensing the vocal folds. Contraction of the dorsal cricoarytenoid muscle dilates the larynx by abducting the arytenoid cartilage and therefore the vocal cords. WikiVet Article: Larynx Incorrect. The lateral cricoarytenoid muscle adducts the vocal processes thereby narrowing the glottis. Contraction of the dorsal cricoarytenoid muscle dilates the larynx by abducting the arytenoid cartilage and therefore the vocal cords. WikiVet Article: Larynx Incorrect. The transverse arytenoid muscle passes between the two arytenoid cartilages and it narrows the glottis. Contraction of the dorsal cricoarytenoid muscle dilates the larynx by abducting the arytenoid cartilage and therefore the vocal cords. WikiVet Article: Larynx Incorrect. The thyroarytenoid muscle alters the tension of the vocal and vestibular folds. Contraction of the dorsal cricoarytenoid muscle dilates the larynx by abducting the arytenoid cartilage and therefore the vocal cords. WikiVet Article: Larynx Correct! Contraction of the dorsal cricoarytenoid muscle dilates the larynx by abducting the arytenoid cartilage and therefore the vocal cords. WikiVet Article: Larynx

Which laryngeal cartilage is ring-shaped?

Please select an option Incorrect. The interarytenoid cartilage is a nodule of hyaline cartilage found between the arytenoid cartilages dorsally. It is the cricoid cartilage which is ring-shaped. WikiVet Article: Larynx Incorrect. The epiglottic cartilage is leaf-shaped and is the most rostral cartilage of the larynx. It is the cricoid cartilage which is ring-shaped. WikiVet Article: Larynx Correct! The cricoid cartilage is ring-shaped. WikiVet Article: Larynx Incorrect. The arytenoid cartilages are a pair of triangular shaped cartilages which articulate with the rostral part of the ring-shaped cricoid cartilage. WikiVet Article: Larynx Incorrect. The thyroid cartilage forms most of the floor of the larynx. It is the cricoid cartilage which is ring-shaped. WikiVet Article: Larynx

You are performing a dental on an eight year old dog in your practice and you decide to extract the dog's upper right second premolar. How would you identify this tooth using the modified Triadan system?

Please select an option Incorrect. This is the upper left second premolar. The correct answer is 106. Link to Veterinary Dentistry Correct! This digit 1 denotes the quadrant i.e. the right upper permanent quadrant. Digits 0 and 6 denote the tooth position within the quadrant and the second premolar is the sixth tooth along from the midline. Link to Veterinary Dentistry Incorrect. This is the lower right second premolar. The correct answer is 106. Link to Veterinary Dentistry Incorrect. This is the lower left second premolar. The correct answer is 106. Link to Veterinary Dentistry Incorrect. This number correctly identifies the upper right second premolar, but the digit 5 denotes the right upper deciduous quadrant and since this is an eight year old dog it will have permanent teeth. The correct answer is 106. Link to Veterinary Dentistry

What is the permanent dental formula of a horse?

Please select an option Correct! In the horse, upper premolar one, or the wolf tooth, is often lacking, hence the upper dental formula of P 3-4. Horses have three upper and three lower molar teeth on each side, which work in a unit along with their premolars. Females usually don't have canines so the formula is often written 1(0)/ 1(0) for mares. WikiVet Article: Dental Formula - Horse Incorrect. The horse only has three lower premolars but usually has an extra upper premolar i.e. premolar one or the wolf tooth. The dental formula should read 2 (I 3/ 3, C 1/ 1, P 3-4/ 3, M 3/ 3).Females usually don't have canines so the formula is often written 1(0)/ 1(0) for mares.
