Major extrinsic muscle is - psoas major, which joins the iliacus m. to form the iliopsoas m. Other "extrinsic" limb muscles are either small (superficial gluteal m.) or they attach to the os coxae which is immobile (psoas minor m. & coccygeus, m.)

Transcribed image text: Question 2 (10 points) Parkinson's disease is a neurodegenerative disease characterized by the progressive loss of neurons in the substantia nigra pars compacta. A. What medical imaging technique would be utilized to figure out if the appropriate neural structures are activated in response to specific stimuli?
Prime Mover, Antagonist, Origin, and Insertion of Prime Mover
The erector spinae is a massive group of muscles that are prime movers of extension, lateral flexion, and spine rotation. It has 3 columns: the iliocostalis, longissimus, and spinalis muscles.
What muscles are used in the neck?
This occurs at the joint just below the skull and uses deep neck flexor muscles as well as the sternocleidomastoid (SCM) muscle. Other neck movements include: rotating the neck from side to side. bending the neck laterally to bring the ear to the shoulder. extending the neck to lift the chin upward.
Why does my neck flex?
Neck flexion is the action of moving your chin down toward your chest. Even though it’s a simple motion, it’s possible to develop pain, tightness, and decreased mobility in this area. Causes may include actions as simple as looking down at your phone repeatedly, holding your head in one position, or sleeping incorrectly.
Why is my neck stiff?
Impaired or limited neck flexion has a variety of causes and usually involves actions that require you to look down often. When it’s the result of looking down at a handheld device, it’s known as text neck. Activities that can cause neck stiffness and limited range of motion include: computer and cellphone use.
How to get rid of tightness in neck?
Rest your arms alongside your body and engage your core muscles to stabilize your spine. Draw your shoulder blades back and down. Slowly draw your chin in toward your chest. Hold for 15–30 seconds.
How to get rid of neck pain?
Neck retraction. This exercise loosens up tight muscles, relieves pain, and reduces spinal pressure. Keep your eyes facing forward the whole time. Place your fingers on your chin to push your head as far backward as possible. Feel the stretch in the back of your neck. Hold for 2–3 seconds before returning to neutral.
How far can you move your neck without pain?
extending the neck to lift the chin upward. In neck flexion, a normal range of motion is 40 to 80 degrees, which is measured by a device called a goniometer. This shows how far you can move your neck without experiencing pain, discomfort, or resistance. Healthy joints, muscles, and bones help to maintain a normal range of motion.
How to get your chin back on your bed?
Hold this position for at least 30 seconds. Release by tucking your chin into your chest and using your arms to shift your body back onto the bed. Do this exercise 1–3 times.
What are the main arteries in the neck?
The common carotid arteries and the vertebral arteries are the major arteries in the neck. Left and right common carotid and vertebral arteries run on each side of the neck. Each common carotid artery branches into two divisions: the internal and external carotid artery. The internal carotid arteries supply blood to the anterior brain, while the external carotid arteries supply blood to the face and neck. Vertebral arteries also pass through the transverse foramen of the cervical spines before merging to form the basilar artery. Vertebral and basilar arteries supply blood to the posterior brain. The basilar artery anastomoses with the internal carotid arteries, and together they form the circle of Willis, which provides blood to the brain. Vertebral arteries also further branch off to give one anterior spinal artery and two posterior spinal arteries. These arteries supply the anterior and the posterior portion of the spinal cord, respectively. There are also numerous smaller arteries throughout the neck, head, and face that branch off from the common carotid and vertebral arteries. [4]
What is the difference between the cervical ganglia and the middle cervical ganglion?
The superior cervical ganglion lies at the C2/C3 intervertebral level , while the middle cervical ganglion lies at the C6/C7 intervertebral level. The interior cervical ganglion is fused with the first thoracic ganglion to create the stellate ganglion at the C7/T1 intervertebral level.
What is the primary motion of the upper portion of the lower cervical unit?
C3 through C7 are known as "typical" cervical vertebrae. The primary motion of the upper portion of the lower cervical unit is rotation (C2-C4) is rotation . The primary motion of the lower portion of the lower cervical unit is side-bending. The description of all spinal and vertebral movements are relative to motions of their anterior and superior surfaces. [1]
What is the function of the cervical spine?
The function of the cervical spine is to stabilize and maintain the head in a position that allows our eyes to be parallel to the ground.[2] This function is crucial for the vestibular function, which assists in balance. The cervical spine allows large movements to scan our surroundings and can adjust to interact with our environment. It also aids in swallowing and helps to elevate the rib cage during inhalation. The vertebral bodies protect the spinal cord and vertebral arteries, and the muscles of the neck protect other neurovascular structures necessary for sustaining life. Any interruption of the proper function of the neck can lead to a critical state and is usually the first thing evaluated in any emergency situation.
Which joint is obliquus superior?
Obliquus capitis superior: head extension at the atlantooccipital joint by bilateral contraction, lateral head flexion (ipsilateral) at the atlantoaxial joint by unilateral contraction
What is cervical flexion?
Cervical flexion:bending the head forward towards the chest.
What are the major veins in the neck?
The major veins in the neck include jugular veins and vertebral veins. Jugular veins diverge into external and internal jugular veins. The external jugular vein sits more superficially. It collects blood from the superficial skull and deep parts of the face. Blood then and drains to the subclavian vein. Blood from the brain, the superficial face, and superficial neck drains into the internal jugular vein. It then merges into the subclavian vein.[4] The vertebral veins also drain blood into the subclavian vein after running through the foramen transversarium.
What are the prime movers of ankle plantar flexion?
What Are the Prime Movers of the Ankle Plantar Flexion? The prime movers of ankle plantar flexion are the soleus and gastrocnemius muscles. These muscles are located at the back of the lower leg and attach from the knee to the heel. The gastrocnemius and soleus together are called the triceps surae. Together, they form a complex of three muscles, ...
What are the muscles that attach to the soleus and gastrocnemius?
The gastrocnemius and soleus together are called the triceps surae. Together, they form a complex of three muscles, because the gastrocnemius has two heads that attach from the knee to the foot through the Achilles tendon. The soleus attaches to the two lower leg bones, the tibia and fibula.
Which muscle is the prime mover in dorsiflexion?
In dorsiflexion, or pulling the toes up, the roles of prime mover and antagonist are reversed. The prime mover in dorsiflexion is the tibialis anterior and the antagonists include the soleus and gastrocnemius muscles. ADVERTISEMENT.
Which muscles are antagonists?
Antagonist muscles lengthen as the prime movers shorten during flexion. The major antagonist is the tibialis anterior, or the shin muscle. The posterior tibialis and the medial, or inner, gastrocnemius work to neutralize the force during plantar flexion of the ankle. The fibularis muscles stabilize the ...
Which muscles fold around each other?
The soleus and gastrocnemius fold around each other, forming a bulge with a cleft at the calf when the muscles are well-developed. Many muscles assist with plantar flexion of the ankle, a movement akin to pointing the toes. The synergist muscles assist the flexion. Antagonist muscles lengthen as the prime movers shorten during flexion.
