Fibre types in human abdominal muscles

Acta Physiologica Scandinavica, 1979
Histochemical muscle fibre composition was studied in biopsies from the four different muscles of the abdominal wall (rectus abdominis, RA, obliquus externus, OE, obliquus internus, OI, and transversus abdominis, Tr) in 13 normal human subjects (9 females and 4 males, age 24–55 years) undergoing gall‐bladder surgery.

Phasic stretch reflex of the abdominal muscles

Experimental Neurology, 1986
This analysis of the abdominal stretch reflex (ASR) evoked by a tap to the abdomen was designed to explore how abdominal motoneurons process signals from respiratory and nonrespiratory sources. We recorded surface EMGs from the external and internal oblique muscles in standing subjects. Amplitudes of the abdominal stretch reflex varied despite constant

Muscle relaxation during abdominal surgery

The American Journal of Surgery, 1980
A self-retaining surgical retractor has been modified by incorporating a strain gauge device linked to a digital display meter. This instrument is capable of continuously monitoring abdominal wall relaxation during surgery and should prove useful in a variety of routine and investigative procedures.

Absence of Abdominal Muscles

Pediatrics, 1957
Opening the June Pediatrics, I noted another article reviewing the clinical and pathologic picture of absence of the abdominal muscles. As this particular review is so current and complete, it would seem repetitious for me to report the several cases I have had.

Mechanics of the abdominal muscles in rabbits and dogs

Respiration Physiology, 1994
In anesthetized, apneic rabbits and dogs, direct tetanic stimulations of the abdominal muscles (AMS) were performed at different tracheal pressures (Ptr) in the supine and upright posture. Lung volume (V), esophageal (Pes) and abdominal pressure (Pab), circumference of the upper and lower lung apposed rib cage (Crc, u and Crc, l) and of the abdomen ...

Rectus Abdominal Muscles Pulled by Coughing

JAMA: The Journal of the American Medical Association, 1972
To the Editor.— While practicing in Yuma, Ariz, I have seen two patients in the last six months who presented with pulled rectus abdominal muscle insertions over the symphysis pubis. Careful questioning of both patients revealed no history of trauma, but both patients had experienced antecedent, prolonged paroxysms of coughing.

Fiber architecture of canine abdominal muscles

Journal of Applied Physiology, 2002
During respiration, abdominal muscles experience loads, not only in the muscle-fiber direction but also transverse to the fibers. We wondered whether the abdominal muscles exhibit a fiber architecture that is similar to the diaphragm muscle, and, therefore, we chose two adjacent muscles: the internal oblique (IO), with about the same muscle length as ...

Intercostal and abdominal muscle afferent influence on caudal medullary expiratory neurons that drive abdominal muscles

Experimental Brain Research, 1989
Our objective was to determine if caudal ventral respiratory group (VRG) expiratory (E) neurons that drive abdominal expiratory motoneurons in the lumbar cord respond to intercostal and lumbar nerve afferent stimulation. Results showed that 92% of medullary E-neurons that were antidromically activated from the upper lumbar cord reduced their activity ...

Abdominal Muscles

One of the main subjects of anatomy education is muscular system anatomy. Muscular system anatomy is the set of muscles that form the skeletal system in the human body and enable the body to move. In this section, the abdominal region extending between the diaphragm above and the pelvis below is discussed.

Electrical muscle stimulation for deep stabilizing muscles in abdominal wall

2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008
Low back pain is associated with dysfunction in recruitment of muscles in the lumbopelvic region. Effective rehabilitation requires preferential activation of deep stabilizing muscle groups. This study was carried out in order to quantify the response of deep stabilizing muscles (transverses abdominis) and superficial muscle in the abdominal wall ...
