Flashcards in Lower limb Deck (89)
List the bones of the foot:
Other important anatomy of the foot (besides bones):
Joints of phalanges and metatarsals
Lower leg bones:
Anatomy of lower limb:
How are bones of the foot similar to bones of the hand?
There are 26 bones in the foot (compared to 27 in the hand) divided into three groups:
7 Tarsals (compared to 8 carpals in the hand)
The dorsum or dorsal surface of the foot is:
The superior surface of the foot.
The plantar surface of the foot is:
Inferior or posterior aspect of the foot.
Phalanges of the foot (or digits) are also called
The phalanges (toes) are numbered:
The first digit of the foot has ____ phalanges and are called_____ & ______.
2/proximal and distal
Second through fifth digit of the foot have ___ phalanges and they are called ____, _____, and ______.
3/proximal, middle and distal.
The head of the phalanx is:
the rounded distal portion.
The body (shaft) of the phalanx is:
The base of the phalanx is:
Expanded proximal portion.
the bones of the instep, numbered 1-5, and consist of a head, body and base.
The 5 metatarsal heads form:
the "ball" of the foot.
Which metatarsal is the shortest and thickest?
The base of the 5th metatarsal contains:
a prominent tuberosity.
The tuberosity on the base of the 5th metatarsal provides for:
attachment of a tendon.
The tuberosity on the base of the 5th metatarsal is a common site for:
The tuberosity on the base of the 5th metatarsal must be:
well visualized on the radiograph.
Interphalangeal joint (IP) is:
Between proximal and distal phalanges of the 1st digit.
Proximal interphalangeal joints (PIP) are:
Between proximal and middle phalanges 2-5.
Distal interphalangeal joints (DIP) are:
Between middle and distal phalanxes 2-5.
Metatarsophalangeal Joint (MTP joint) is:
Between heads of metatarsals and bases of phalanges.
Tarsometatarsal Joint (TMT joint) is:
Between tarsals and bases of metatarsals.
Small, detached bones embedded in certain tendons.
Sesamoid bones of the lower limb:
Largest is patella, Two on plantar surface at head of 1st metatarsal. Medial side is tibial sesamoid, lateral side is fibular sesamoid.
Sesamoid bones of the upper limb:
Most often found on palmar surface near MCP joint.
