Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

6.7K
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Skeletal Muscle Anatomy

94.1K
Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.

Motor Unit Stimulation01:20

Motor Unit Stimulation

4.4K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Muscle Contraction01:10

Muscle Contraction

9.2K
In skeletal muscles, acetylcholine is released by nerve terminals at the motor endplate—the point of synaptic communication between motor neurons and muscle fibers. The binding of acetylcholine to its receptors on the sarcolemma allows entry of sodium ions into the cell and triggers an action potential in the muscle cell. Thus, electrical signals from the brain are transmitted to the muscle. Subsequently, the enzyme acetylcholinesterase breaks down acetylcholine to prevent excessive...

Excitation-Contraction Coupling in Skeletal Muscles

17.0K
Excitation-contraction coupling is a series of events that occur between generating an action potential and initiating a muscle contraction. It occurs at the triad, a structure found in skeletal muscle fibers that comprise a T-tubule and terminal cisternae of the sarcoplasmic reticulum on each side. These triads are visible in longitudinally sectioned muscle fibers. They are typically located at the A-I junction — the junction between the A and I bands of the sarcomere.
When an action...

Area of Science:

  • Neuroscience
  • Musculoskeletal Biology
  • Regenerative Medicine

Background:

  • Tendon metabolism regulation and response to loading are not fully understood.
  • Tendon innervation, beyond sensory roles, influences homeostasis via neuromediators.
  • Healthy tendons have innervation in surrounding structures, not the tendon proper.

Purpose of the Study:

  • To explore the regulatory role of tendon innervation in tendon homeostasis and disease.
  • To investigate the impact of nerve ingrowth on tendon repair and tendinopathy.
  • To assess the link between metabolic disorders, neuronal factors, and tendon healing.

Main Methods:

  • Review of current literature on tendon innervation and metabolism.
  • Analysis of anatomical distribution of nerves in healthy and injured tendons.
  • Examination of the role of neuromediators in tendon healing and pathology.

Main Results:

  • Innervation regulates tendon homeostasis through efferent pathways and neuromediators.
  • Nerve ingrowth into the tendon proper occurs during injury and repair, influencing regeneration.
  • Excessive innervation in tendinopathy correlates with inflammation, pain, and degeneration.
  • Diabetes impairs tendon healing due to dysregulated neuronal growth factors.

Conclusions:

  • Tendon innervation is crucial for metabolic regulation and healing.
  • Targeting the peripheral nervous system offers potential therapies for tendon disorders.
  • Understanding neuro-immune-metabolic interactions is key for treating tendinopathy.
