Muscles that Move the Head01:19

Muscles that Move the Head

6.5K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin

1.3K
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
The binding of dantrolene to the RYR1...

Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

5.3K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Skeletal Muscle Relaxants: Therapeutic Uses01:31

Skeletal Muscle Relaxants: Therapeutic Uses

1.1K
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

Articulations of the Vertebral Column01:28

Articulations of the Vertebral Column

3.4K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Cranial Nerves: Types Part II01:22

Cranial Nerves: Types Part II

5.6K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)
Cranial nerve VII, or the facial nerve,...

Summary
This summary is machine-generated.

Cervical dystonia patients effectively modulate neck stabilization despite altered afferent feedback, challenging previous hypotheses. Their ability to adapt responses to mechanical perturbations is similar to healthy individuals.

Area of Science:

  • Neuroscience
  • Biomechanics
  • Motor Control

Background:

  • Effective sensorimotor integration is crucial for adapting neck stabilization strategies.
  • Cervical dystonia may impair the ability to modulate afferent feedback for neck stabilization.

Purpose of the Study:

  • To evaluate if cervical dystonia patients have impaired afferent feedback modulation for neck stabilization compared to controls.
  • To assess how frequency content of mechanical perturbations affects neck stabilization in cervical dystonia.

Main Methods:

  • Applied anterior-posterior torso perturbations (low and high bandwidth) to seated subjects.
  • Recorded head-neck kinematics and muscular activity during tasks requiring head posture control.
  • Compared responses between cervical dystonia patients and age-matched healthy controls.

Main Results:

  • Patients and controls showed similar kinematic and muscular responses to perturbations.
  • Neck stiffness and afferent feedback decreased with high bandwidth perturbations in both groups.
  • Cervical dystonia patients exhibited increased neck stiffness during a head-forward task due to heightened afferent feedback.

Conclusions:

  • The study does not support the hypothesis of impaired afferent feedback modulation in cervical dystonia patients.
  • Both kinematic and muscular head-neck stabilization modulation remained unaffected in patients.
  • Findings suggest preserved sensorimotor integration for neck stabilization in cervical dystonia.
