What are the main parts of the femur?
Proximal epiphysis, shaft, inferior epiphysis
The femur consists of three main parts.
What structures are found in the proximal epiphysis of the femur?
Head with fovea, neck, trochanters (greater, lesser), intertrochanteric crest and line
These structures are critical for articulation and muscle attachment.
What features are present on the shaft of the femur?
Linea aspera (medial and lateral lips, pectineal line, popliteal surface), gluteal tuberosity
The shaft provides a robust structure for muscle attachment and support.
What structures are found in the inferior epiphysis of the femur?
Condyles, epicondyles, intercondylar fossa, patellar surface
These features are important for knee joint articulation.
Fill in the blank: The head of the femur contains a _______.
fovea
The fovea is a small pit that allows for ligament attachment.
True or False: The gluteal tuberosity is located on the inferior epiphysis of the femur.
False
The gluteal tuberosity is located on the shaft of the femur.
What is the function of the intertrochanteric crest?
Provides attachment for muscles
It is crucial for the stability and function of the hip joint.
What is the patella?
A small bone that articulates with the distal femur at the knee joint
The patella is also known as the kneecap.
What surface of the patella articulates with the distal femur?
Articular surface
This surface allows for movement and stability at the knee joint.
What is the anterior surface of the patella?
The front surface of the patella
This surface is typically smooth and faces outward.
What attaches to the base of the patella?
Quadriceps tendon
The quadriceps tendon connects the quadriceps muscle to the patella.
What attaches to the apex of the patella?
Patellar ligament
The patellar ligament connects the patella to the tibia.
What are the main components of the proximal epiphysis of the tibia?
Tibial plateau, condyles, intercondylar eminence
The proximal epiphysis is the upper end of the tibia, which articulates with the femur.
What structures are associated with the proximal epiphysis of the tibia?
Tuberosity, soleal line
These structures provide attachment points for muscles and ligaments.
What are the surfaces of the tibial shaft?
Lateral, medial, posterior
The shaft is the long, cylindrical part of the tibia.
What are the borders of the tibial shaft?
Medial, interosseus, anterior
These borders are important for muscle attachment and structural integrity.
What structures are found in the distal epiphysis of the tibia?
Medial malleolus, fibular notch
The distal epiphysis is the lower end of the tibia, which interacts with the ankle joint.
What is the fibula?
A long, thin bone located on the lateral side of the leg.
What are the main parts of the fibula?
Head, neck, shaft, lateral malleolus.
What are the surfaces of the fibula?
Lateral, medial, posterior.
What are the borders of the fibula?
Lateral, interosseus, anterior.
Fill in the blank: The _______ is the distal end of the fibula.
lateral malleolus
True or False: The fibula is primarily a weight-bearing bone.
False
What is the function of the lateral malleolus?
Provides stability to the ankle joint.
What are the main components of the foot skeleton?
Tarsals, Metatarsals, Phalanges
The foot skeleton is divided into three main parts: tarsals, metatarsals, and phalanges.
What are the key bones in the tarsals?
Talus, Calcaneus, Cuboid, Navicular, Cuneiform (lateral, intermediate, medial)
The tarsals consist of seven bones: talus, calcaneus, cuboid, navicular, and three cuneiform bones.
What are the components of the talus bone?
Head, neck, body, articular surfaces
The talus includes specific articular surfaces: anterior calcaneal, middle calcaneal, posterior calcaneal, trochlea, medial and lateral malleolar, and navicular.
What are the main features of the calcaneus?
Tuber, body, sustentaculum, articular surfaces
The calcaneus has several articular surfaces: anterior talar, posterior talar, middle talar, and cuboid.
List the types of phalanges in the foot.
Proximal, middle, distal
The phalanges are categorized into proximal, middle, and distal sections.
What are the structural parts of the metatarsals?
Base, body, head
Each metatarsal consists of three main parts: the base, body, and head.
Fill in the blank: The _______ is the largest bone in the foot and forms the heel.
Calcaneus
The calcaneus is also known as the heel bone.
True or False: The talus does not have a direct muscular attachment.
True
The talus serves as a key structure in the ankle joint but does not have direct muscular attachments.
