Health Q2

MCL

prevents the leg from moving from side to side, works together with the LCL

PCL

Attaches to posterior tibia
Prevents backward sliding of tibia and forward sliding of femur. thicker compared to ACL.

Sacrum

connects the two hip bones, stabilization from behind.

ischium

the curved bone forming the base of each half of the pelvis. seat down bone.

Pelvic Gridle

ilium, ischium, pubis (hip bone)

patella

kneecap, prevent the knees from hyper extension

malleolus

the rounded bony protuberance on each side of the ankle

shin splint

a painful condition caused by the muscle tearing away from the tibia. The pain usually disappears after warm up

shin bone hairline fracture

pain either increases or stay the same after warming up.

Tarsals

ankle bones. Includes
- talus
- navicular bone
- calcaneus

calcaneus

heel bone, where the AST (achilles tendon) is attached

metatarsals

foot bones

Phalanges

toes

ACL

holds sides and top and bottom of knees together
can be injured by twisting or tearing. X shaped. Thinner compared to PCL. Prevents the leg from moving forward and backward.

Meniscus

provides cushion in between the knees

lateral meniscus

cartilage in the knee

Meniscus tear

Impact form outside of the knee or not knowing how to properly decelerate or land a jump.

iliac crest

very prominant

sacroiliac joint

responsible to hold the sacrum and ilic crest together

pubic symphysis

Provide stability for the hip bone in the front

Acetabulum

large socket in the pelvic bone for the head of the femur

neck of femur

usually where fracture occur

shaft of femur

body of femur

Fibula

The lateral and smaller bone of the lower leg, calf bone

tibia

the medial and larger bone of the lower leg (shin bone)

tibiotalar joint

joint between the tibia and the talus

Talus

ankle bone. the only bone in contact with the lower leg.

LCL

prevents the leg from moving from side to side, works together with the MCL

medial meniscus

C-shaped cartilage in the knee. the outer 1/3 has more blood supply, therefore faster at recovery. the inner 2/3 of the medial meniscus has little to none blood supply therefore hard to recover form injuries.

knee joint

includes
patella
meniscus
ligaments

labrum

cartilage between femur head and acetabulum

lateral malleolus

the longer malleolus

medial malleolus

the shorter malleolus

navicular bone

sentisve with lots of nerves in the tarsals
