Q

Digastric - Anterior Belly Origin

A

Digastric fossa of mandible

2
Q

Digastric - Anterior Belly Insertion

A

Intermediate tendon to body and greater horn of hyoid

3
Q

Digastric - Anterior Belly Innervation

A

Nerve to mylohyoid, a branch of inferior alveolar nerve

4
Q

Digastric - Anterior Belly Action

A

Working with infrahyoid muscles, depresses mandible against resistance; elevates and steadies hyoid during swallowing and speaking

Q

Digastric - Posterior Belly Insertion

A

Intermediate tendon to body and greater horn of hyoid

7
Q

Digastric - Posterior Belly Innervation

A

Digastric branch of (preparotid) facial nerve (CN VII)

8
Q

Digastric - Posterior Belly Action

A

Working with infrahyoid muscles, depresses mandible against resistance; elevates and steadies hyoid during swallowing and speaking

9
Q

Mylohyoid Origin

A

Mylohyoid line of mandible

10
Q

Mylohyoid Insertion

A

Mylohyoid raphe and body of hyoid

11
Q

Mylohyoid Innervation

A

Nerve to mylohyoid, a branch of inferior alveolar nerve (from mandibular nerve, CN V3)

12
Q

Mylohyoid Action

A

Elevates hyoid, floor of mouth, and tongue during swallowing and speaking

13
Q

Stylohyoid Origin

A

Stylohyoid process of temporal bone

14
Q

Stylohyoid Insertion

A

Body of hyoid

15
Q

Stylohyoid Innervation

A

Stylohyoid branch of (preparotid) facial nerve (CN VII)

16
Q

Stylohyoid Action

A

Elevates and retracts hyoid, thus elongating floor of mouth

17
Q

hypoglossal nerve and ansa cervicalis C1 run blank but blank

A

together, are separate

18
Q

the blank artery is winding because the TMJ is so active

A

facial

19
Q

the scalenes are all innervated by blank

A

anterior rami

20
Q

same innervation means similar blank

A

development

21
Q

blank emerges between anterior and middle scalene

A

brachial plexus
