ANA1201 Week 8: Knee and Lower Leg Practical Manual

Vocabulary practice flashcards covering the muscles, bony landmarks, ligaments, bursae, fat pads, and anatomical regions of the knee and lower leg from the ANA1201 Week 8 practical manual.

Rectus Femoris

A biarticulate and dual action muscle of the anterior thigh compartment that acts on both the hip and the knee.

Tensor Fascia Latae

The muscle with the most lateral origin among the listed anterior compartment muscles.

Sartorius

A muscle of the anterior compartment that produces dual actions across both the hip and knee joints.

Vastus Lateralis

An anterior compartment quadriceps muscle situated laterally along the thigh.

Vastus Intermedius

An anterior compartment muscle situated deeply between vastus lateralis and vastus medialis.

Vastus Medialis

An anterior compartment quadriceps muscle situated medially along the thigh.

Pectineus

An anterior compartment muscle listed medial to sartorius that produces action at the hip.

Adductor Longus

A muscle of the anterior/medial group that acts on the hip joint, located medial to pectineus.

Adductor Brevis

An adductor muscle of the anterior/medial group that acts on the hip.

Biceps Femoris (long head)

A posterior compartment hamstring muscle that acts on both the hip and knee joints.

Biceps Femoris (short head)

A posterior compartment muscle that acts specifically on the knee joint.

Semitendinosis

A posterior compartment hamstring muscle that produces actions across both the hip and knee joints.

Semimembranosus

A posterior compartment hamstring muscle situated medially that acts across both the hip and knee joints.

Gastrocnemius

A two-headed muscle (lateral and medial heads) of the posterior compartment that acts on both the knee and the talocrural joint.

Soleus

A posterior compartment lower leg muscle that acts on the talocrural joint.

Plantaris

A posterior compartment muscle that acts on both the knee and the talocrural joint.

Popliteus

A posterior compartment muscle located deep at the back of the knee joint.

Adductor Tubercle

A distinct bony landmark located on the distal medial aspect of the femur that serves as an attachment site.

Intracondylar Fossa

The deep bony depression located between the condyles on the posterior aspect of the femur.

Patella Surface

The smooth anterior bony area on the distal femur that articulates with the patella.

Tubercles of Intercondylar Eminence

Elevated bony projections located between the articular facets on the superior surface of the tibia.

Tibial Tuberosity

An anterior bony landmark of the proximal tibia that serves as an attachment site.

Soleal Line

An oblique bony ridge situated on the posterior surface of the tibia.

Styloid Process of Fibula

The pointed bony projection extending superiorly from the head of the fibula.

Apex of Patella

The inferior, pointed bony landmark of the patella.

Base of Patella

The broad superior border or landmark of the patella.

Anterior Cruciate Ligament (ACL)

An intracapsular knee ligament connecting the femur and tibia that stabilizes and resists displacement of the knee.

Posterior Cruciate Ligament (PCL)

An intracapsular knee ligament connecting the femur and tibia that resists knee movement and displacement.

Medial Collateral Ligament (MCL)

A ligament connecting the medial epicondyle of the femur to the tibia, resisting medial and valgus stress.

Lateral Collateral Ligament (LCL)

A ligament of the knee that connects the lateral femur to the head of the fibula, resisting varus forces.

Superior Tibiofibular Ligament

A ligament that connects the proximal ends of the tibia and fibula at the superior tibiofibular joint.

Meniscus (Medial and Lateral)

Crescent-shaped fibrocartilaginous structures situated within the knee joint between the femoral condyles and tibial plateau.

Patella Tendon

A fibrous band extending from the patella to the tibial tuberosity.

Suprapatella Bursa

A synovial bursa positioned superior to the patella between the quadriceps tendon and the distal femur.

Prepatellar Bursa

A superficial bursa situated anteriorly between the skin and the anterior surface of the patella.

Infrapatella Bursa

A bursa located inferior to the patella associated with the patellar tendon.

Pes Anserine Bursa

A bursa situated on the proximal medial side of the tibia beneath the conjoined tendons of the pes anserinus.

Infrapatella Fat Pads

A pad of adipose tissue situated below the patella and posterior to the patellar tendon.

Popliteal Fossa

The diamond-shaped anatomical space located behind the knee joint on the posterior lower extremity.
