Rectus Abdominis |
Right and Left side most powerful spinal flexor |
|
Tendirous inscriptions |
another name for the lines that create a six pack |
|
External oblique overview |
Most superficial runs diagonally from lower 8 rids to linea alba to pelvis thin flat covering of abs |
|
Rectus Abdominus action |
spinal flexion |
|
external oblique action |
Lateral flexion and rotation |
|
Internal oblique |
connects from ribs 9-12 at 90 degree angle |
|
Transverse abdominus |
also know as the corset muscle deepest Helps with posture and stabilization Aids in breathing |
|
Linea Alba |
The line or crease that runs down the middle of your abs and serves as a connector. |
|
Erector Spine |
Starts as one muscle in the lower back Then splits into three: 1. Spinalis (medial) thoracic spine 2. Longissimus (intermideate) thoracic cervial border 3. Iliocostalis (lateral) top 4 ribs main stabilizer of spine |
|
What makes up the Transbersospinalis Group |
Semispinalis Multifidus Rotatores |
|
Semispinalis action and placement |
Spinal extension only in thoracic and cervical spine |
|
Multifidus action and placement |
spine extension/stablization
lumbar spine |
|
Rottores |
Connects vertebrae to ribs stabilization |
|
What is the deep spinal group and what is it made of |
individual muscles that connect vertebrae together Interspinalis intertransversales Quadratus Lumborum |
|
Intertransversales |
connects transverse process stabilization |
|
Interspinalis |
connects spinous process, straight down back |
|
Quadratus Lumborum |
Flat muscle in lumbar |
|
Thoracic Kyphosis |
Hunching of the back |
|
Cervical Lordosis |
forward neck |
|
Lumbar Lordosis |
Sway Back Causes: -tight sacrum -forced turnout
|
|
Scoliosis |
Can be structural or non structural ( non can be fixed without surgery) types of curve: -S curve (more serious) -C curve |
|
Herniated disk |
Cause -as you get older the water content of disk lessens and can not absorb as much shock. then pushes part of disk out of vertebrae Symptoms: -pain or numbness in back and back of thigh, Treatment: -if disk has completely deteriorated then they will replace it -most cases will heal themselves |
|
Sciatica |
pain caused by pressure on sciatic nerve Cause: -tightness in legs or butt usually on your right or dominate side |
|
Trapezius |
-connects down the length of spine Upper: -fibers are down and lateral -upward rotation, sapular elevation, adduction Middle: -sacpular adduction Lower: -sacpular depression -upward rotation -adduciton |
|
Levator Scapulae |
-small, lyes under the upper trapezius -upward rotation |
|
Rhomboids |
-Runs under traps -minor above major small and weaker -connects inner edge of scapula to spine -scapular elevation, adduction, downward rotation |
|
Serratus Major |
-from ribs 1-8, to under scapula to medial edge -attaches back to front of thorax -upward rotation, lower fibers aid scapular depression, scapular adduction |
|
Pectoralis Minor |
-goes to front of ribs, under the pec major, -abduction, downward rotation and depression |
|
Rotator Cuff |
-made of 4 muscles (Supraspinatus, Infraspinatus, Teres Minor, Subscapularis) -helps humerus stay in place -forms hood around head of humerus -stabilize humerus head |
|
Pectoralis Major |
-starts at inner clavicle, sternum, costal cartilage of upper 6 ribs -attaches at humerus -front of armpit is the attachment of pec major to humerus -Shoulder adduction, internal rotation (pushing, throwing and punching) |
|
Deltoid |
-attaches to clavicle and wraps around shoulder to middle of humerus Anterior: -shoulder flexion -adduction -internal rotation Middle: -abduction Posterior -extension -abduction -external rotation |
|
Coracobrachialis |
-beneath pec major -shoulder flexion and adduction |
|
Latissimus Dorsi (Lats) |
-broadest muscle of back. -attaches to humerus via flat tenon that makes back of armpit -adduction, shoulder extension, internal rotation |
|
Teres Major |
-runs across top part of lats and assists with its movement |
|
Biceps |
superficial, two heads (short and long), flexion |
|
Supinator |
raidoulnar supination attaches radius to ulna |
|
Brachialis |
under bicep, elbow flexion |
|
Brachioradialis |
elbow flexion returns arm to natural position |
|
Pronator Teres |
Radioulnar pronator Elbow flexion |
|
Pronator Quadratus |
pulls radius over ulna |
|
Triceps |

|
Anconeus |
Elbow extension |
|
Tennis Elbow |
Tendonitis of the elbow caused by over use. Brace and rest will help, in the worst scenario surgery is needed. |
|
Carpal Tunnel |
numbness of fingers due to over use and weakness the median nerve become inflamed and puts pressure on nerve in carpal tunnel |
