#1
Which muscle is primarily responsible for neck extension?
Sternocleidomastoid
Trapezius
Scalene muscles
Splenius capitis
#2
The trapezius muscle assists in neck extension by:
Elevating the scapula
Rotating the scapula
Extending the head
Depressing the scapula
#3
Which of the following is not a function of the posterior neck muscles?
Neck extension
Neck flexion
Lateral neck flexion
Rotation of the head
#4
Which muscle is not typically involved in the movement of neck extension?
Splenius cervicis
Levator scapulae
Sternocleidomastoid
Trapezius
#5
Which muscle group includes the iliocostalis, longissimus, and spinalis muscles?
Suboccipital group
Erector spinae group
Scalene group
Prevertebral group
#6
Which of the following muscles is not involved in neck extension?
Levator scapulae
Erector spinae
Semispinalis capitis
Platysma
#7
Which muscle works synergistically with the splenius capitis during neck extension?
Sternocleidomastoid
Semispinalis capitis
Longissimus capitis
Scalene muscles
#8
What is the role of the erector spinae in neck extension?
It primarily flexes the neck
It stabilizes the spine
It extends the vertebral column and head
It rotates the neck
#9
Which muscle is directly beneath the sternocleidomastoid and assists in neck extension?
Trapezius
Levator scapulae
Longus colli
Longus capitis
#10
In addition to the splenius capitis, which other muscle is considered a major extensor of the head?
Splenius cervicis
Semispinalis cervicis
Longissimus thoracis
Semispinalis thoracis
#11
Advanced: The deep muscles of the neck involved in extension, such as the semispinalis capitis, belong to which muscle group?
The anterior vertebral muscles
The lateral vertebral muscles
The suboccipital muscles
The posterior vertebral muscles
#12
The suboccipital muscles are important for which aspect of neck extension?
Fine-tuning the movement
Primary extension force
Lateral flexion assistance
Anterior flexion
#13
Advanced: How does the function of the longissimus capitis differ from that of the scalene muscles in the context of neck movements?
The longissimus capitis extends and laterally flexes the neck, while the scalene muscles primarily assist in breathing.
The longissimus capitis primarily assists in breathing, while the scalene muscles extend and laterally flex the neck.
Both are primarily involved in neck extension.
Both are primarily involved in neck flexion.
#14
Advanced: Which of the following muscles does not insert into the mastoid process of the temporal bone?
Splenius capitis
Longissimus capitis
Sternocleidomastoid
Semispinalis capitis
#15
What is the unique action of the longissimus cervicis in neck movements?
It is the primary muscle for neck flexion
It assists in lateral neck flexion and extension
It solely rotates the neck
It primarily stabilizes the neck without moving it
