What is the Lat Muscle? The lat muscle, or latissimus dorsii is a large, roughly triangular skeletal muscle which stretches from near the spinal column across the back and up under the armpit to join the humerus, the upper arm bone. Each person has two latissimus dorsii muscles, one on each side of the body. The lat is one of a group of muscles responsible for several movements of the arm and shoulder joint. Muscles of the back are among some of the largest in the human body, and the lat muscle is the largest of these.

muscle erector muscle of spine a name given the fibers of the more superficial of the deep muscles of the back, originating from the sacrum, spines of the lumbar and the eleventh and twelfth thoracic vertebrae, and the iliac crest, which split and insert as the iliocostal, longissimus, and spinal muscles.oke muscle's Muscles of the two eyes which simultaneously contract to turn the eyes in a given direction. Example: the medial rectus of the right eye and the lateral rectus of the left eye when turning the eyes to the left.

Trapezius Muscle Click to read more below. The trapezius is one of the major muscles of the back and is responsible for moving, rotating, and stabilizing the scapula (shoulder blade) and extending the head at the neck. It is a wide, flat, superficial muscle that covers most of the upper back and the posterior of the neck.hen other muscles hold the scapula in place, the superior fibers of both trapezius muscles can extend the head at the neck by pulling the occipital bone closer to the scapula. The middle fibers work to retract and adduct the scapula by pulling the shoulder blade closer to the spine.

How does the detrusor muscle impact urination? When it is time to urinate, the detrusor muscle contracts to allow the urine to come out. If the detrusor muscle is not working normally, urination will be impacted. If the detrusor muscle is overactive, it tries to squeeze the urine out even when you are not ready to urinate.This can feel like pain in the bladder area.his is sometimes called overactive bladder or overactive detrusor muscle. If the detrusor muscle does not squeeze or is overstretched, it can be difficult to get urine out even when you are trying to urinate.

What is an Extensor Muscle? An extensor muscle is a muscle that works to extend or straighten a body part, effectively enlarging the angle between body parts.Examples of extensor muscles include the muscles that straighten the elbow or the knee.ll of these muscles are anchored to the bone of the upper arm, the humerus, by a common tendon, known as the common extensor tendon. These muscles serve primarily to extend the wrist and fingers. Ad. The main muscle that works to straighten the arm by extending the elbow joint is the triceps brachii extensor muscle.

Shoulder Anatomy 1 These muscles retract and elevate the scapula. 2  Teres major muscle originates from posterior surface of the inferior angle of the scapula and attaches the medial lip of the intertubercular sulcus which lies on the anterior surface of the humerus. 3  This muscle extends and medially rotates the humerus.

URINARY BLADDER ANATOMY This is the middle layer of the structural design of the bladder. The third layer, the muscularis layer, is created by the interlacing of three smooth muscle layers. These muscles together are known as the detrusor muscle. The detrusor muscle undergoes a transformation when it reaches the neck of the urinary bladder.

[TA] muscle of anterior (flexor) compartment of arm; origin, coracoid process of scapula; insertion, middle of medial border of humerus; action, adducts and flexes the arm; acts as a shunt muscle in resisting downward dislocation of shoulder joint; nerve supply, musculocutaneous.

Major Muscles on the Front of the Body Teres major muscle. is a muscle of the arm and one of six scapulohumeral muscles. It is not part of the rotator cuff. The teres major is a medial rotator and adductor of the humerus and assists the latissimus dorsi in drawing the previously raised humerus down and backward (extension, but not hyper extension).t’s the largest and the most outermost of the three flat muscles of the outside front of the abdomen. It has limited actions in both flexion and rotation of the vertebral column. One side of the obliques contracting can create lateral flexion.

Splenius Capitis Muscle The muscle lies deep to the sternocleidomastoid in its superior portion, and deep to trapezius in its inferior portion. The muscle acts as a shaker of the head, it causes neck extension and lateral flexion. Other muscles that extend and rotate the head include the semispinalis capitis and semispinalis cervicis (also laterally flexes the head). The superior portion of trapezius also acts as a lateral flexor of the neck.

What is detrusor hyperreflexia? Detrusor hyperreflexia occurs when there is a neurological cause for involuntary bladder contractions. Spasms result from damage to the spinal cord and nervous system.Reasons for hyperreflexia instability include:• Spina bifida (a birth defect of the spinal column).• Multiple sclerosis (a neurologoic disorder).etrusor hyperreflexia occurs when there is a neurological cause for involuntary bladder contractions.

Latissimus Dorsi The Latissimus Dorsi Muscle’s origin attachment point is the lowers spinal vertebrae, the lower ribs and lumber vertebrae and its insertion point of attachment is on the front side top of the Humerus, specifically the bicipital groove, which is achieved by its tendons wrapping around the underside of the humerus.

Overactive Bladder The most important muscle in the bladder is the detrusor muscle. In normal circumstances, when the bladder fills with urine, it can stretch to hold the urine. When the volume in the bladder reaches close to 300 cc, the stretch in the wall of the bladder can trigger a nerve response to initiate urination (micturition).

Trapezius Muscle Trapezius Muscle. The trapezius is one of the major muscles of the back and is responsible for moving, rotating, and stabilizing the scapula (shoulder blade) and extending the head at the neck. It is a wide, flat, superficial muscle that covers most of the upper back and the posterior of the neck. Like most other muscles, there are two trapezius muscles – a left and a right trapezius – that are symmetrical and meet at the vertebral column.

Urinary bladder Detrusor muscle [edit]. The detrusor muscle is a layer of the urinary bladder wall made of smooth muscle fibers arranged in spiral, longitudinal, and circular bundles. hollow muscular, and distensible (or elastic) organ, the bladder sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra. There is no exact measurement for the volume of the human bladder, but different sources mention 500 mL (~17 oz) to 1000 mL (~34 oz).

- The biceps brachii is an agonist for elbow flexion. It is assisted by the brachialis and the brachioradialis. These are the agonists of elbow flexion, all of which are capable of flexing the elbow joint to some extent.uring elbow flexion, the angular component, the one that makes the radius move around the elbow joint, is the swing component. The brachioradialis is an example of a shunt muscle, which is able to provide a compressive force. A certain muscle may exert a stronger spurt or shunt force.

The Deep Neck Flexors The Deep Neck Flexors What are the deep neck flexor muscles? The deep neck flexors are a group of muscles that are responsible for forward bending and side-bending of the neck.These muscles are also very important for supporting the weight of the head against gravity and stabilizing the neck during various body movements.eep Neck Flexor Exercises. The deep neck flexors can be activated by a simple nodding movement of the head on the neck called a chin-tuck. The tucking the chin activates the deep flexor muscles and moves the chin closer to the ‘Adam’s apple’ (Thyroid cartilage).

Muscle Roles and Contraction Types 4. Fixator: The fixator in a movement is the muscle(s) that stabilises the origin of the agonist and the joint that the origin spans (moves over) in order to help the agonist function most effectively. In the bicep curl this would be the rotator cuff muscles, the ‘guardians of the shoulder joint’.. Agonist: The agonist in a movement is the muscle(s) that provides the major force to complete the movement. Because of this agonists are known as the ‘prime movers’. In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below.

How does the detrusor muscle impact urination? The detrusor muscle is what most people call the bladder.. When the bladder is filling with urine, the detrusor muscle remains relaxed and stretches to hold the urine.
