Body Flashcards
What are tendons
Tendons join muscle to bone
What are ligaments
Ligament joins bone to bone
Abduct
outward, take it away and lift up
Adduct
inwards, brings back in
What is synovial fluid?
Synovial fluid sits between the cartilage
What is lateral flexion?
Moving the head or trunk sideways away from the mid line
What is extension?
Restoring a body part to its anatomical position after flexion
What is flexion?
Moving two bones towards each other
What is medial/internal rotation?
Rotation towards the centre of the body
What is lateral/external rotation?
Rotation away from the centre of the body
What is protraction?
Movement to the front
What is retraction?
Movement backward
lateral
further away from the midline
medial
close to the midline
above
superior
below
inferior
front
anterior
back
posterior
right in the middle
saggittal
frontal
coronal
horizontal rotation
transverse
These types of movements add to the midline
adductions
These types of movements take away from the midline
abductions
flexion example
fetal position when the entire body is fully flexed
extension example
upward arm in side angle
horizontally flexed
lateral flexion
thigh bone
femur
knee cap
patella
lower leg bones
fibula, tibia
heel
calcaneous
back “wings”
scapulae
cartilage
cushions the ends of joints, absorb impact and reduces friction
synovial fluid
brings nutrients and oxygen to the joints because blood supply does not support this.
Pec Major
responsible for flexing the arm from extended position. It can internally rotate. Major muscle used in plank.
“six pack”
rectus abdominus (attaches from the xiphoid process, at ribs and pubic bones.)
2 types of obliques?
External oblique and internal oblique
Rectus abdominus is superficial to the…
external obliques
External obliques are superficial to the…
internal obliques
Pigeon can help…
External rotators
Extend the knee and help with hip flexion
quadraceps
rectus means
straight
Adductors consist of…
- adductor brevis
- adductor longis
- adductor magnus
- gricilis
- Pectineus
Hamstrings consist of…
semitendinosus (front) semimembranosus (back) Biceps femoris (extends hip…flexes the knee)
ESG
Erector spine group (muscles along the spine that help with lateral flexion)
Lats - help you to stay upright
Latissimus Dorci
Helps the latissimus dorci
Terris major
Extends the elbow joint..attaches to the ulna
triceps
- 3 factors that determine mobility
- Bone shape
- Ligaments
- Muscles around joints
Name and show three planes of anatomical movement
Saggital - Flexion/Extension; Coronal - Adduction/Abduction; Transvers - Rotation
What muscle if tight prevents the hips from squaring in V1?
Psoas, hip flexor;
What do the quads and hamstrings do?
Quads flex the leg at the hip and extend the leg at the knee; The hamstrings flex the knee.
reciprocal inhibition
When the central nervous system sends a message to the agonist (muscle causing movement) to contract, the tension in the antagonist (muscle opposing movement) is inhibited by impulses from motor neurons, and thus must simultaneously relax
What is the non-anatomical name for Ischial Tuberosities?
Sitting bones
What do the biceps and the triceps do?
Biceps: supinates the forearm; flexes the arm at the elbow; Triceps: extends the arm at the elbow.
What do the quads and hamstrings do?
Quads flex the leg at the hip and extend the leg at the knee; The hamstrings flex the knee.
