Which Muscle Inserts On The Basihyoid Bone In The Horse?
The sternohyoideus muscle inserts on the basihyoid bone and lingual process and, in combination with the sternothyroideus muscle, pulls the basihyoid bone caudally (5).
Which muscle inserts on the hyoid bone?
Geniohyoid muscle
Geniohyoid originates at the genial tubercle (inferior mental spine) of the mandible. The slender muscle continues inferiorly to insert on the anterior surface of the body of the hyoid bone. The bilaterally paired muscle lies between mylohyoid and genioglossus (base of the tongue).
How many muscles attach to hyoid bone?
The two geniohyoid muscles originate close to the point at which the two halves of the lower jaw meet; the fibres of the muscles extend downward and backward, close to the central line, to be inserted into the body of the hyoid bone. Contraction of the muscles pulls the hyoid bone upward and forward.
How are muscles attached to bones horses?
Tendons attach each end of a muscle to a bone. At selected points, they are located within sheaths that allow them to move easily. Ligaments are also tough cords formed of connective tissue. Unlike tendons, they can stretch to some extent.
What is the hyoid bone in a horse?
The hyoid apparatus is a Y-shaped group of bones that joins onto the skull and provides attachment for several muscles, including the tongue. The muscles that control the tongue and airways, including those that attach to the hyoid apparatus are small and sit deep between the horse’s ‘jawbones’ (the mandibular rami).
What muscles are attached to the hyoid bone quizlet?
Match
- digastricus. depresses mandible.
- mylohyoid. elevates hyoid bone.
- stylohyoid. elevates larynx.
- thyrohyoid. depresses hyoid.
- omohyoid. depresses hyoid/larynx.
- sternohyoid. depresses hyoid/larynx.
- sternothyroid. depresses hyoid/larynx.
- splenius capitis/cervicis. extends, rotates head.
On what bone does the digastric muscle insert?
the hyoid bone
The Digastric Muscle: Insertion
The digastric muscle inserts on the hyoid bone by the tendon that connects the anterior and posterior bellies of this muscle.
What muscle attaches to the sternum and the hyoid bones?
Sternohyoid muscle
The sternohyoid muscle is a thin, narrow muscle attaching the hyoid bone to the sternum. It is one of the paired strap muscles of the infrahyoid muscles.
What group of muscles is found between the hyoid bone and mandible?
The classification of the suprahyoid muscles includes four muscles that run from the mandible to the hyoid bone. These four muscles come together to form the floor of the mouth. The paired mylohyoid muscle is one of these muscles, along with the geniohyoid muscle, digastric muscle, and stylohyoid muscle.
Which of the following muscles does not directly attach to the hyoid?
The sternothyroid muscle originates from the dorsal surface of the manubrium and inserts on the oblique line of thyroid cartilage. That is why the sternothyroid is the only hyoid muscle that does not directly attach to the hyoid bone.
What muscles do you use to mount a horse?
Which Muscles are Used During Horse Riding?
- Transverse Abdominus. This muscle helps stabilise between your hips, your ribs, and your pelvis.
- Obliques. These are our turning muscles.
- Psoas. The psoas is one of the most important hip flexor muscles involved during riding.
- Iliacus.
- Piriformis.
- Gluteus Maximus and Glute Medius.
Where is the insertion of the Sternocephalicus muscles of the horse?
Sternocephalicus: originates from the cariniform cartilage of the sternum, inserts into the caudal side of the mandible.
What tissue connects bone to bone?
The tendons are the connective tissues which connect bones to muscles and ligaments are the connective tissues which connect bones to bones.
Why is it called hyoid bone?
The name hyoid derives from the Greek word “hyodeides,” which means “shaped like the letter Upsilon.” Although dubbed as an unconventional bone, the hyoid being a part of the hyoid-larynx complex is indeed a bone of clinical and forensic significance.
What are the 5 hyoid apparatus?
The hyoid apparatus consists of the paired stylohyoid, epihyoid, ceratohyoid, thryohyoid bones, and the central basihyoid bone. (Fig. 25.11). The stylohyoid bone articulates with the petrous part of the temporal bone, allowing the stylohyoid bones to move cranial to caudal, in a pendulous manner.
Is the hyoid bone attached to any other bones?
Famously, the hyoid bone is the only bone in humans that does not articulate with any other bone, but only has muscular, ligamentous, and cartilaginous attachments.
Where do the suprahyoid muscles insert?
The suprahyoid muscles are four muscles located above the hyoid bone in the neck. They are the digastric, stylohyoid, geniohyoid, and mylohyoid muscles.
Function.
| Muscle | Digastric (posterior belly) |
|---|---|
| Origin | Mastoid notch |
| Insertion | Intermediate Tendon |
| Innervation | Facial nerve (CN VII) |
Where is the hyoid muscle?
The hyoid muscles are superficial muscles in the neck which attach to the hyoid bone. They are grouped according to their position to the hyoid bone, the suprahyoid muscles lie above the hyoid bone and the infrahyoid muscles lie beneath it.
Where does Thyrohyoid muscle attach?
hyoid bone
The thyrohyoid muscle is a small skeletal muscle on the neck. It originates from the lamina of the thyroid cartilage, and inserts into the greater cornu of the hyoid bone.
What is the insertion of the digastric?
Digastric muscle
| Origin | Anterior belly: digastric fossa of mandible Posterior belly: mastoid notch of temporal bone |
|---|---|
| Insertion | Body of hyoid bone (via intermediate tendon and its fibrous sling) |
| Action | Depresses mandible Elevates hyoid bone during chewing, swallowing |
What is the digastric muscle do?
The digastric muscle functions during swallowing, chewing, and speech. The anterior belly of the digastric is one of the three suprahyoid muscles which stabilizes the hyoid during swallowing, an action critical in protecting the airway while eating.
