L3 A&P - UNIT 1 - S3

Section 3: Postural and core stability

QuestionAnswer
name the 4 ligaments of the spine Anterior longitudinal - Posterior longitudinal - Interspinous - Intertransverse
which 2 spine ligaments prevent excess spine flexion Posterior longitudinal - Interspinous
which spine ligament prevents excess extension of the spine Anterior longitudinal
which spine ligament prevents excess lateral flexion of the spine Intertransverse
Name the 3 deep spine muscles Intertransversarii - Interspinalis - Rotatores
Name the six main core muscles Transversus abdominis - Internal / External obliques - Multifidus - Diaphragm - Pelvic floor
Which core muscle wraps around the body attaching to the lower ribs and the pelvis. It functions by compressing the abdominal contents and increasing intra-abdominal pressure to stabilise the spine Transversus abdominis
Which core muscle situated over the transversus abdominis. They help compress the abdominal contents and provide rotation and lateral flexion of the spine Internal obliques
Which core muscle situated situated over the internal obliques and transversus abdominis and wrap around the body. They help compress the abdominal contents and provide rotation and lateral flexion of the spine External obliques
Which core muscle made of a series of smaller muscles connects the spinous processes of the spine to the transverse processes two or three vertebrae below help with rotation & extension of the spine & to hold the lumbar segments in an extended position Multifidus
Which primary core muscle that initiates breathing contracts downwards and helps create intra-abdominal pressure to help stabilise the spine in conjunction with all the other muscles in the group Diaphragm
Which core muscle made of several small muscles acts like a hammock at the base of the body to hold the organs. They contract together with the diaphragm & other core muscles to create intra-abdominal pressure & stabilise the spine. Pelvic floor
Core musculature that is poorly prepared to function in unison can lead to chronic wear and tear or to possible acute injury and trauma of the spine
which 3 layers of trunk muscles need to function together for effective core movement and stability Deep, middle and outer layer
which trunk muscle layer is more responsible for the large movements that are possible at the core. outer
which trunk muscle set that joins the pubis, ribs and sternum creates spinal flexion forces ? RA rectus abdominis
which internal/external (particularly) combine with the abdominals and the erector spinae to create rotational movement of the spine. obliques
the ability of the trunk to support the forces of the arms and legs in the safest, strongest and most effective manner is known as g*** c*** f******* good core function
Commonly observed postures in people who adopt long-term seated positions can cause what kyphosis
Flexing at the knees and lacking flexion at the hip are both signs the h********** may be shortened, which affects spinal position hamstrings
3 Types of stretching ? Static - Dynamic - PNF
what does the abbreviation PNF stand for proprioceptive neuromuscular facilitation
which type of stretching entails Maintenance stretch – maintains flexibility. Development stretch – increases flexibility Static stretching
which type of stretching entails Effective as part of warm-up. Promotes blood flow and elasticity. Reduces risk of injury. Dynamic stretching
which type of stretching entails Uses phases of static stretching followed by muscular contraction. Should only be applied to thoroughly warm muscles and by an experienced practitioner. Proprioceptive neuromuscular facilitation stretching (PNF)
