What is knee joint made up of
knee joint is comprised of which muscles
•predominantly two-joint muscles which also cross and act at the hip joint.
•rectus femoris of the quadriceps group,
•sartorius and TFL muscles.
The gastrocnemius is another two joint which also crosses at the ankle joint.
two joint muscles
some muscles create action or movement across two joints
i.e hamstrings which crosses both hip and knees
tensor fasciae latae
softening (degeneration) of cartilage
name the major movements ad secondary movements possible at the knee joint.
The gastrocnemius the major muscle of the posterior shin functions to extend the foot (plantar flexion).
It ties in with the hamstrings at the knee joint where they are both involved in the knee joint flexion. in addition the insertion of the gastrocnemius on the femur helps to improve greater flexibility.
how do the quadriceps and hamstrings work together in a lung exercise
The muscle mass of the quadriceps is much greater than that the hamstrings the quadriceps should always be stronger than the hamstrings in almost all instances because of their workload is much larger larger.
Quadriceps help and walking running and jumping activities
ankle joint is made up of
ankle joint is made up of what muscles
•(gastrocnemius )is the major ankle extensor muscle of the Shin, •(soleus) has a similar functions to the gastrocnemius,
•(tibialis anterior) is the main muscle of the anterior side of the Shin.
What movements happen at the ankle
the gastrocnemius is the major ankle extensor muscle of the shin the tendons from the two heads of the muscle run diagonally downward to attach to the achiles tendons , Solus is slightly wider than the gastrocnemius and together they form a functional unit sometimes called the triceps surae Tibialis tendon at the lower in crosses the ankle joint and inserts on the inner in under surface of the foot.
which muscle plays a role maintaining the arch of the foot.
Extension beyond anatomical position or normal limit
Briefly explain the role of the spine in the body
•It provides the main framework and foundation for most of the movements of the body and extremities
movements of the spine include
• Movements of one vertebra on another ,separated by the intervertebral discs
•movements between the facet of successive vertebrae which are freely moveable
•intervertebral discs allow slight movement and function in shock absorption
What role does the rectus abdominis, transverse abdominis, and obliques play in stabilizing the spine.
• These abdominal musculatures acts to prevent the vertebral column from continually hyper extending
What role does the pelvis play in relation to the "trunk" and lower extremities
•when legs are fixed: pelvis changes position relativ to the femur
•when lower body is free to move or is air born: pelvis moves with movement in the lumbar spine
explain the relationship between the abdominal muscles and hip flexors
•the abdominal muscles (rectus abdominis, external / internal obliques) and the hip flexors (iliopsoas ,pectineus and rectus femoris) work together in order to create max ROM in your ability to raise the legs as high as possible.
list the rotator cuff muscles
•hypothetical force by which a body of positive mass would rebel a body of negative mass
• responsible for posture
•shoulder pain caused by connective tissue (a tendon) rubbing on a shoulder blade
the shoulder girdle is made up of which bones
the shoulder girdle is responsible for which movements of the scapula
muscles of the shoulder girdle
which muscles serve as primary movers of the arm at the shoulder joint
•the long and short head of biceps and the long head of the triceps on the posterior side.
shoulder impingement may result from the squeezing of which tendon ? which exercise should be done with caution as a result.
•lateral arm raises
how do the shoulder girdle and shoulder joint work together throughout movement
the shoulder joint muscles are responsible for moving the arm while the shoulder girdle muscles (which work in synchronization with the shoulder joint muscles.) are responsible for moving the scapula (and clavicle) muscles work together and closely with one another to ensure smooth ROM in the shoulder joint.
What muscles are involved in military press exercise
•clavicular pectoralis major of chest
•anterior deltoid of the shoulder
•trapezius and serratus anterior muscles of the shoulder girdle
•all are prime movers for their actions
the elbow joint is made up of which bones
•ends of humerus
the elbow joint is comprised of which anterior and posterior muscles
the radioulnar joint is made up of which bones
•a combination of three joints located at the wrists, elbow and in between the ulna and radius bones
radioulnar joint is made up of which muscles
which movements occur at the radioulnar joint
•consists of pronation and supination
the wrist is made up of which bones
•ends of the radius and ulna bones of the forearm with the carpal bones of the hand
What movements occur at the wrist joint
•flexion and extension/ hyperextension
•radial and ulna flexion (abduction) and adduction respectively
What common injury occurs at the elbow?
how is it (tendinitis) cause
•causes from tendons from their hands due to poor grip ( wrist flexor muscles)
what's a solution to (tendinitis)
•maintan a strong firm correct grip on the bar and keep wrist flexed or stiff
the wrist joint is comprised of which muscles
•extensor carpi radialis longus
•extensor Carpi radialis brevis
•extensor carpi ulnaris
