Bones of the Foot/Ankle
The foot consists of how many bones.
26
Movements of the foot are produced by _______ & _______ muscles of the foot.
Extrinsic
Intrinsic
______ attach muscle to bone.
Tendons
_______ attaches bone to bone.
Ligaments
One primary function of the bones of the body.
Protect vital organs.
Create movement.
Produce blood cells.
Store minerals.
The first toe (hallux) is made up of how many phalanges?
2
________ muscles originate in the lower leg.
Extrinsic
This tendon flexes the foot upward (dorsiflexion).
Anterior tibialis tendon
The three lateral ligaments of the ankle joint:
Anterior talofibular ligament
Posterior talofibular ligament
Calcaneofibular ligament
Bones are classified by 4 different shapes.
Long
Short
Flat
Irregular
The largest & strongest metatarsal.
First metatarsal.
Extrinsic muscle movements include:
Dorsiflexion
Plantar flexion
Inversion
Eversion
This tendon is vulnerable to injury, due to its limited blood supply and the high tensions placed on it.
Achilles tendon
The deltoid ligament is the primary resistance to foot _______.
eversion
The thickened distal ends of both the tibia & fibula.
Lateral malleolus & medial malleolus.
The largest tarsal bone (the attachment site for the Achilles tendon).
Calcaneus
Two (posterior) extrinsic muscles that produce plantar flexion:
Gastrocnemius
Soleus
The peroneal longus tendon attaches at which metatarsal bone?
first metatarsal bone
The deltoid ligament is comprised of how many ligaments?
4
The four bones of the ankle joint.
Distal portion of the tibia (medial malleolus).
Distal portion of the fibula (lateral malleolus).
Talus.
Calcaneus.
Prevents forward slipping of the tibia during locomotion.
Talus bone.
Intrinsic muscles of the foot originate in the ______ and are responsible for the 4 movements of the _________, which are:
Foot
Phalanges
Flexion
Extension
ABduction
ADduction
The Achilles tendon originates at the ________ and attaches at the _________.
gastrocnemius
calcaneus
The high ankle ligaments are also called ________ and the ligament that articulates the tibia and fibula is called:
syndesmotic
anterior inferior tibiofibular ligament.
A thick white band of fibrous tissue, originating at the calcaneus, that supports the foot against downward forces:
Plantar Fascia
