Mouse extensor digitorum longus and soleus show distinctive ultrastructural changes induced by veratrine
(2002-07-01)
We investigated whether veratrine (5 μl, 10 ng/kg) injected into the mouse extensor digitorum longus (EDL) (fast-twitch) and soleus (SOL) (slow-twitch) muscles provokes distinctive ultrastructural disturbances 15, 30 and ...
Histochemical study of muscle fiber types in Synbranchus marmoratus Bloch, 1795
(1996-01-01)
The myotomal muscle of Synbranchus marmoratus was investigated using histochemical and immunohistochemical reactions. This musculature is composed of a superficial red compartment, uniformly distributed around the trunk ...
Histoenzymological and ultrastructural changes in lateral muscle fibers of Oreochromis niloticus (Teleostei: Cichlidae) after local injection of veratrine
(2001-12-01)
The effects of veratrine have been investigated in mammalian, amphibian, and crustacean muscle, but not in fish. In this work, the action of veratrine was studied in the lateral muscle of the freshwater teleost Oreochromis ...
Electromyographic study of the trapezius (pars media) and rhomboideus major muscles in free movements of the head
(1980-12-01)
The authors studied the trapezius (pars media) and rhomboideus major muscles in movements of flexion, extension, inclination and rotation of the head. The electromyographic records demonstrated that referred muscles are ...
Electromyographic study of the trapezius (middle portion) and rhomboideus major muscles in movements of the trunk
(1980-01-01)
The authors studied the trapezius (middle portion) and rhomboideus major muscles in movements of flexion, extension, inclination and rotation of the trunk. The electromyographic records demonstrate that such muscles show ...
Electromyographic study of the trapezius (pars media) and rhomboideus major muscles during respiration
(1980-12-01)
The authors studied the trapezius (pars media) and rhomboideus major muscles during deep inspiration and expiration. The electromyographic records demonstrated that these muscles showed no activity in either phase of breathing.
Satellite cells and myonuclei in long‐term denervated rat muscles
(1995-01-01)
Background: The percentage of satellite cells rapidly decreases in aneurally regenerating soleus muscles of rat. Also denervation of intact muscles causes fiber loss and regeneration, but the fate of satellite cells is ...
Morphological aspects of muscle regeneration in the Nile tilapia (Oreochromis niloticus)
(2004-07-01)
The aim of our study was to analyze the morphological events in the skeletal muscle of the Nile tilapia (Oreochromis niloticus) after a traumatic lesion. Thirty-two fish were used, on which a small longitudinal incision ...
Morphological aspects of rabbit masseter muscle after cervical sympathectomy
(2001-08-07)
The objective of this paper was to study the effect of sympathetic innervation on morphological and histochemical aspects of skeletal muscle tissue. Rabbit masseter muscle was studied using histochemical and immunohistochemical ...
