| the feature located between the posterior inferior iliac spine and the ischial spine on the coxal bone is the _________ __________ __________. nerves from the lumosacral plexus as well as blood vessels pass through this notch. | greater sciatic notch |
| the feature located between the ischial spine and the ischial tuberosity on the coxal bone is the ___________ _________ _________. nerves from the lumbosacral plexus as weel as blood vessels pass through this notch | lesser sciatic notch |
| openings on the sacrum called ___________ _____________ provide passageways for nerves and blood vessels. there are four of these openings on each side of the sacrum. | sacral foramina |
| by definition all synovial are diarthroric and have a wide range of motion. _______ joints, including the joints between the sacrum and coxal bones, however, have limited sliding motions. | plane |
| the large muscle of the posterior hip that originates on the ilium, sacrum, and coccyx and acts to extends the leg at the hip and rotate the thigh laterally is the _________ _________. | gluteus maximus |
| the muscle of the posterior region of the upper leg that originates on ischial tuberosity and the linea aspera of the femur and acts to flex the lower leg and extend the upper leg is the _________ __________ | biceps femoris |
| the muscle on the lateral side of the leg that inserts by means of a long tendon (the fascia of the iliotibial tract) on to the lateral surface of the tibia is the ___________ ___________ __________ | tensor fascial latae |
| a knob-like process is usually larger than a tubercle is called a ____________. on the ischium, this feature serves as the origin for the semimembranosus and semitendinosus muscles | tuberosity |
| the muscle group of the medial region of the upper leg that orginates on the pubis and ischium and inserts on to the linea aspera if the femur is the ________ group | adductor |
| the muscle of the posterior region of the upper leg that inserts on to the medial sondyle of the tibia and acts to extend the upper leg and rotate the thigh medially is the ___________ | semimembranosus |
| the long muscle of the leg that originates ont he anterior superior iliac spine and inserts on to the medial surface of the tibia is the ____________ | sartorius |
| the vertebral foramina of the fused sacral vertebrae from the ___________ ____________ | sacral canal |
| when classifying bones based on shape, the innominate bone is classified as a __________ bone. | flat |
| the muscle of the anterior of the upper leg that originates on the anterior inferior iliac spine and acts to flex the upper leg is the __________ _____________ | rectus femoris |
| the 2 muscles of the hip that inserts on to the greater trochanter of the femur and act to abduct and rotate the thigh medially are the _________ ___________ and the ___________ ____________ | gluteus medius; gluteus minimus |
| a tiny pit or depression in a bone is called a ___________. an example of this feature on the femur is called the ________ _________ and serves as an attachment site for ligaments. | fovea; fovea capitis |
| the joint between the acetabulum and the head of the femur is an example of a specific type of synovial joint called a ________ ____ ________ joint. movement in all planes, including rotaion, is possible at this tyoe of joint. | ball and socket |
| the muscle of the medial region of the upper leg that originates on the pubis below the symphysis and acts to adduct the thigh is the ___________ | gracillis |
| the muscle of the posterior region of the upper leg that inserts on to the medial surface of the tibia and acts to extend the upper leg is the ___________ | semitendinosus |
| the muscle that originates on the iliac fossa that acts to flex the thigh is the ____________ | illiacus |
| the superior articular facets of the sarcum articular with the ________ ________ _______ of the fifth lumbar vertebrae to form a plane joint | inferior articular facets |
| a narrow ridge on a bone is called a ________. an example of this feature on the femur is called the ________ _________ and serves as an attachment site for muscles that adduct the thigh | linea; linea aspera |
| the pubis bones from a __________ type of cartilaginous joint. based on its degree of movement, this is a type of ________________ joint | symphysis; amphiarthrotic |
| when the lumbar vertebrae acts as the origin instead of the insertion, the ______ ________ muscle acts to flex teh thigh instead of the ttrunk | psoas major |
| ORIGIN- pubis and pubic symphysis, ischial tuberosity INSERTION- linea aspera and posterior surface of femur ACTION- adducts, flexes, extends thigh; rotates thigh laterally | adductor group |
| ORIGIN- ischial tuberosity, linea aspera of femur INSERTION- head of fibula, lateral condyle of tibia ACTION- extends thigh, rotates thigh laterally | biceps femoris |
| ORIGIN- sacrum, coccyx, posterior surface of ilium INSERTION- gluteal tuberoscity of femur and iliotibial band ACTION- extends thigh at hip, rotates thigh laterally | gluteus medius |
| ORIGIN- lateral surface of ilium INSERTION- greater trochanter of femur ACTION- abducts thigh, rotates thigh medially | gluteus medius |
| ORIGIN- lateral surface of ilium INSERTION- greater trochanter of femur ACTION- abducts thigh, rotates thigh medially | gluteus minimus |
| ORIGIN- lower edge of pubic symphysis INSERTION- medial surface of tibia ACTION- adducts | gracilis |
| ORIGIN- iliac fossa INSERTION- lesser trochanter of femur ACTION- flexes thigh | iliacus |
| ORIGIN- transverse processes of lumbar vertebrae INSERTION- lesser trochanter of femur ACTION- flexes thigh * | psoas major |
| ORIGIN- anterior inferior iliac spine, margin of acetabulum INSERTION- tibial tuberosity (via patellar tendon, patella, and patellar ligament) ACTION- flexes thigh | rectus femoris |
| ORIGIN- anterior superior iliac spine INSERTION- medial surface of tibia ACTION- extends thogh; rotates thigh medially | sartorius |
| ORIGUN- ischial tuberosity INSERTION- medial condyle of tibia ACTION- extends thigh; rotates thigh medially | semimembranosus |
| *when the lumbar vertebrae serves as the origin of this muscle, it acts to flex the thigh; in this case this muscle can be grouped with the iliacus muscle to form the iliopsoas group | psoas major |
| ORIGIN- ischial tuberosity INSERTION- medial surface of tibia distal to medial condyle ACTION- extends thigh; rotates thigh medially | semitendinosus |
| ORIGIN- anterior surface of iliac crest INSERTION- lateral (via fascia of iliotibial band) ACTION- abducts, flexes thigh; rotates thigh medially | tensor fasciae latae |
