an input signal. The monosynaptic myotatic stretch reflex is the most crucial reflex for the maintenance of the erect body posture in humans. For the well-known knee-jerk response‚ there is latency of around 30 ms between striking (stretching) the tendon of the quadriceps and the muscle contraction. The reflex involves a number of segments in the SC. Factors that contribute to this latency in the reflex arc are: 1- Speed of transduction at the sensory receptor. This is most rapid when the receptor

10.1 OVERVIEW OF MUSCULAR TISSUE Types of muscular tissue There are 3 types of muscular tissue: skeletal‚ cardiac‚ & smooth. All 3 may share some things but they differ from one another in their microscopic anatomy‚ location‚ & how they are controlled by the nervous and endocrine systems Skeletal muscle tissue function of most is to move bones of the skeleton (are few that attach to other structures ex--the skin). Muscle tissue is striated b/c alternating light and dark protein bands (striations)

is a surgical operation in which a ligament in the medial elbow is replaced with a tendon from elsewhere in the body (often from the forearm‚ hamstring‚ or foot of the patient).” B. To go in-depth‚ UCL Reconstruction or Tommy John Surgery is where a surgeon uses a tendon graft to replace the UCL‚ which is located is on the inside of the persons elbow. The tendon graft is used to replace the damaged or tore tendon in the elbow‚ usually coming from another part of the body where it is not necessary

tendonitis‚ also known as “impingement syndrome “occurs when the rotator cuff gets irritated. They say this issue is arises because rotator cuff weakness causes the humorous to ride up and pinch the cuff.

Proprioceptors are specialized receptors located throughout the body within tendons‚ muscles and joints that provide sensory information about the state of muscle contraction‚ the position of body limbs‚ and body posture and balance This feedback and control over muscles is provided primarily by the afferent input from two sensory receptors: 1.) Golgi Tendon Organs (GTOS) -Sensory receptors that terminate where tendons join to muscle fibre -Serve as a kind of tension detection device for the muscle

The extensors of the knee are the quadriceps group. The quads include the rectus femoris‚ and the vastus lateralis‚ intermedius‚ and medialis. This muscle group shares a common tendon at insertion. The patellar tendon inserts at the tibial tuberosity‚ and within this tendon lies the patella. The patella is anterior to the femur-tibia articulation‚ and this sesmoid bone increases the leverage of the quads by acting as a pulley. The major contributor to the stability of the

Due to such a low tensile capacity‚ flexural cracks develop at early stages of loading. In order to reduce or prevent such cracks from developing‚ a concentric or eccentric force is imposed in the longitudinal direction of the structural element. This force prevents the cracks
