Lab #9: Pelvis and Hip Anatomy

These flashcards cover key terms and definitions related to the anatomy of the pelvis and hip, intended to help students prepare for examinations.

Pelvis

The bony structure at the base of the spine that supports the abdomen and houses the reproductive organs.

Acetabulum

The socket in the pelvis that receives the head of the femur to form the hip joint.

Iliac crest

The upper margin of the ilium, the largest bone of the pelvis.

Ischium

The lower and back part of the hip bone that supports body weight when sitting.

Pubis

The front portion of the pelvic bone.

Greater sciatic notch

An indentation on the posterior of the pelvis allowing nerves and blood vessels to pass through.

Head of the femur

The rounded proximal end of the femur that fits into the acetabulum.

Lesser trochanter

A small, posterior-facing projection on the femur for muscle attachment.

Quadriceps muscles

A group of muscles on the front of the thigh that extend the knee.

ASIS

Anterior Superior Iliac Spine, a bony prominence on the ilium.

PSIS

Posterior Superior Iliac Spine, a bony prominence on the posterior of the ilium.

Psoas muscle

A major muscle that bridges the spine and hip, important for hip flexion.

Gluteal muscles

Muscles located in the buttocks, primarily responsible for hip movement.

Rectus femoris

The only quadriceps muscle that crosses the hip joint, acting on both the hip and knee.

Gracilis

A hip adductor muscle that also crosses the knee joint.

Sartorius

The longest muscle in the human body, aiding in hip and knee movement.

Vastus lateralis

One of the four quadriceps muscles, located on the outer thigh.

Vastus medialis

One of the quadriceps muscles located on the inner thigh.

Vastus intermedius

The quadriceps muscle located beneath the rectus femoris.

Biceps femoris

The lateral muscle of the hamstring group aiding in knee flexion and external rotation.

Popliteal space

The diamond-shaped space located at the back of the knee joint.

Obturator foramen

A large opening in the pelvic bone that allows nerves and blood vessels to pass.

Ischial tuberosity

The bony protrusion of the ischium where muscles and ligaments attach.

Femur

The longest bone in the human body, forming the thigh.

Epicondyles

Bony protrusions on the distal femur that provide attachment for ligaments.

Linea aspera

A ridge on the posterior surface of the femur for muscle attachment.

Greater trochanter

A large, bony protrusion on the femur for muscle attachment at the hip.

Lateral condyle

The outer bony surface at the end of the femur that articulates with the tibia.

Medial condyle

The inner bony surface at the end of the femur that articulates with the tibia.

Hip abduction

The movement of the leg away from the midline of the body.

Hip adduction

The movement of the leg toward the midline of the body.
