Progress in Neurobiology, 1998
Abdominal muscles serve many roles; in addition to breathing, especially at higher levels of chemical drive or at increased end-expiratory lung volumes, they are responsible for, or contribute to, such protective reflexes as cough, sneeze, and vomiting, generate the high intra-abdominal pressures necessary for defecation and parturition, are active ...

Fiber architecture of canine abdominal muscles [PDF]
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 ...

Hernia Due to Banding of the Abdominal Muscles
Archives of Surgery, 1968SUPERIMPOSED parallel slits between bands of the internal oblique and transversus abdominis muscles occasionally open to allow formation of a hernia at the level of the semicircular line of Douglas, which enters a shallow subaponeurotic space lateral to the rectus sheath and deep to the aponeurosis of the external oblique.

Fibre types in human abdominal muscles
Acta Physiologica Scandinavica, 1979Histochemical 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, 1986This 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

TRANSVERSE AND MUSCLE-SPLITTING ABDOMINAL INCISIONS
Archives of Surgery, 1953A RECENT survey of over 500 certified surgeons in this country revealed that only about 26% are employing transverse or muscle-splitting abdominal incisions for the common types of abdominal operations.1It appears therefore that the majority of surgeons and most of the other physicians performing surgery are using midline or paramedian incisions.

Muscle relaxation during abdominal surgery
The American Journal of Surgery, 1980A 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.

Stretch reflexes in human abdominal muscles
Experimental Brain Research, 2004Homonymous and heteronymous reflex connections of the abdominal muscles were investigated by the application of a tap to the muscle belly and observation of surface electromyographic responses. Reflex responses of the following abdominal muscles were investigated both ipsilateral and contralateral to the tap: rectus abdominis (RA), external oblique (EO)

Mechanics of the abdominal muscles in rabbits and dogs
Respiration Physiology, 1994In 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 ...

The role of the abdominal muscles in breathing [PDF]
, 1991 Nine tracheotomized dogs were chronically instrumented with sonomicrometer length measurement transducers and fine wire EMG electrodes in each of the four abdominal muscles: transversus abdominis (TA), internal oblique (IO), external oblique (EO) and rectus abdominis (RA).
