 Muscle Tissue and Muscles
These include the skeletal muscles which are under voluntary control and are made of striated muscle tissue, the visceral muscles which are under involuntary control and are made of smooth muscle tissue, and cardiac muscle tissue which is found only in the heart.
After a muscle contracts, ATP (produced in the muscle cells’ mitochondria) is needed to relax the muscle and return the actin and myosin filaments to their normal positions.
Muscle contraction is initiated when an electrical impulse from a nerve cell reaches its associated muscle cell(s), causing positively- and negatively-charged ions to switch places all along the muscle cell (fiber).

Muscles that are abductors move body parts away from each other or from the trunk of the body itself.
Abductor comes from Latin abducere, which is built of the prefix ab-, “away,” and the verb ducere, “to bring.” Adductor muscles, in contrast, bring body parts together or bring them closer to the body.
It is a group of adductor muscles in the inner thigh, for example, that allows a rider to sit firmly astride a horse.

For the measurement of the postoperative muscle strength in abduction, the anterosuperior iliac spine and both thighs were immobilised to prevent false motion of the pelvis.
Each muscle strength value in Newtons (N) was converted to a ratio of strength to body weight (N/kg), and a mean was calculated from the 3 measurements.10 The percentage of strength to body weight ratio of the affected side was calculated with respect to the normal side.
This percentage is known as the muscle strength ratio, which was subsequently used in the comparisons.7 The measurements of abductor muscle strength were performed by the same author.

 Dissection of deep hip and tail of the opossum, BAA 289L 2004
The muscles looked more continuous than those in the opossum’s tail.  The opossum’s tail muscles segments were much shorter than the rat’s and the muscles were larger and thicker.
Juvenile opossums tend to hang by their tails more often than do adult individuals.During normal terrestrial walking, the tail is curled ventrally [3].  Hanging upside down by the tail leaves the animal fairly vulnerable and it is important that the animal be able to resume a normal quadrupedal stance quickly.
The crurococcygeus and femorococcygeus muscles can flex the tail laterally and move the hind-limbs posteriorly when the animal is hanging by the tail.  The ability to move the hind-limbs posteriorly while suspended by the tail allows the animal to grasp the branch it is suspended from and quickly hoist itself back onto that branch [4].

 Hip Muscle Force Problem Page 2
The diagram is not completely accurate because the direction of the hip abductor muscle force is represented as being vertical.
In fact, the hip abductor muscle force is acting at an angle of 70 degrees relative to the horizontal (see skeletal diagram on previous page).
the rotary component is that part of the hip abductor muscle force that is acting perpendicular to the moment arm (i.e., vertical in this case).

 A muscle force's effect on the hip during unilateral stance
The hip abductors (vector A) act during unilateral stance to oppose the hip adductor moment that gravity produces, and to keep the pelvis level.
Because the abductor muscles' force exceeds that of the superincumbent body weight, most of the compression that the hip joint surface experiences during single limb stance, walking, or running actually comes from muscle action.
They accomplish this in a manner similar to the one people use whey they cannot develop abductor muscle force, by altering their posture and alignment to reduce the moment arm of gravity's force on the hip joint.

At this level, the investing fascia of the abductor is thicker laterally because of the reinforcement from the interfasicular ligament in continuity with the medial intermuscular septum.
When it reaches the lower border of the abductor hallucis, it turns and courses laterally, passing 5.5 mm anterior to the medial calcaneal tuberosity (or spur) and between the quadratus and the underlying flexor brevis until it reaches its distal target of the abductor digiti minimi.
Using a senn retractor, retract the abductor muscle belly dorsally and then plantarly to release the fascia between the abductor and quadratus plantae.

 Modifications of baropodograms after transcutaneous electric stimulation of the abductor hallucis muscle in humans ...
METHODS: The abductor hallucis muscle in 1 foot was subjected to transcutaneous electrical stimulation (20 min) while the subject was standing erect on the floor.
RESULTS: Electrical abductor hallucis muscle stimulation induced, on the stimulation side, a post-contraction state easily detected on baropodograms as the increased plantar pressure on the anterior-medial part of the sole, and lateral displacements of the anterior maximal pressure point and the foot thrust center.
These mechanical signs, consistent with foot inversion, induce external rotation of the leg and pelvic rotation on the stimulated side, leading to contralateral plantar-pressure changes: decreased maximal pressure point and thrust in the posterior part of the footprint and lateral displacement of the foot thrust center.

 Hip biomechanics and the control of posture
Learn how gravitational and muscle forces (not just moments) affect the hip joint surface (the interface between the femoral head and the acetabulum) during unilateral stance.
Because hip abductor activity is necessary to stabilize the hip in the frontal plane during unilateral stance, including the stance phase of walking, people with hip abductor weakness (note the relatively short vector M in the figure below) have a problem.
The force originates on the side opposite the hip whose abductor muscles (vector M) are weak.
