foot plantar(腳掌)
 
 
medial longitudinal arch(內側縱弓)
 
 
 
 
 
 
lateral longitudinal arch(外側縱弓)

即腳掌的部分
 
 
 
 
 
 
Talus(距骨)
 
 
 
 
 
唯一與小腿骨相接的足部骨頭,可分成head() neck()body()三部分
 
 
 
 
 
 
head():可與前端之navicular(舟狀骨)相關節
 
 
 
 
 
 
Body():上表面的突起處為滑車(trochlea);後下方有groove for tendon of the flexor hallucis longus(拇長屈肌肌腱溝)
 
 
 
 
Superior articular facet(上關節面):接tibia下端
Medial articular facet(
內關節面):接tibia(脛骨)medial malleolus(內踝)
Lateral articular facet(
外關節面):接fibula(腓骨)lateral malleolus(外踝)
 
sulcus tali (距骨溝):將其隔成前部與後部
 
 
 
 
 
 
前部:有兩個較小的facet關節面(anterior calcaneal surface(前跟骨表面)middle calcaneal surface(中跟骨表面))Calcaneus(跟骨)相接
 
 
 
 
 
 
後部:有一個較大的facet(posterior calcaneal surface(後跟骨表面))Calcaneus(跟骨)相接,形成posterior talocalcaneal joint(距跟骨關節)
 
 
 
 
 
 
Calcaneus(跟骨)
 
 
 
 
calcaneal tuberosity(跟骨粗隆):接觸地面的構造,供archilles tendon(阿基里斯肌腱)附著
 
soleus muscle(比目魚肌)gastrocnemius muscle(腓腸肌)在小腿根部合為archilles tendon(阿基里斯肌腱)
 
 
 
 
sustentaculum tali(載距突)
 
groove for tendon of the flexor hallucis longus(拇長屈肌肌腱溝)
 
 
上表面為middle talar articular surface(中距骨關節面)
 
fibular trochlea(腓腸肌滑車)
 
groove for fibularis longus tendon(腓腸肌肌腱溝)
 
 
 
 
calcaneal sulcus(跟骨溝):將anterior talar articular surface(前距骨關節面)anterior,middle talar articular surface(中距骨關節面)posterior talar articular surface(後距骨關節面)分開
 
 
 
 
 
 
Articular surface for cuboid bone(骰子骨關節面):位在跟骨前方,是Calcaneus(跟骨)cuboid(骰子骨)相接的位置
 
 
 
 
 
 
navicular(舟狀骨)
Tuberosity of the navicular(舟狀骨粗隆): 位於navicular(舟狀骨)內側面,Tibialis posterior tendon(脛後肌的肌腱)附著
 
 
 
 
 
 
cuboid(骰子骨)
a. 前:與第四和第五蹠骨相接
b.
後:與Calcaneus(跟骨)相接
c.
內:前側面與楔形骨相接,後側面與舟狀骨相接
d.
外:形成tuberosity(粗隆),下表面前方有Tenden of Fibularis longus(腓骨長肌的肌腱)通過的溝
 
 
 
 
 
 
Cuneiforms(楔形骨)
a. 前:分別與medialintermediatelateral相對應的第一、第二、第三蹠骨相接
b.
後:三塊楔形骨皆與舟狀骨相接
c.
外:外側楔形骨和骰子骨相接
 
 
 
 
Tarsometatarsal joint(跗蹠關節):骰子骨和楔形骨與前方的蹠骨形成的關節
Transverse tarsal joint(
橫跗關節):距舟關節和跟骰關節
 
medial cuneiform(內楔狀骨)
 
 
 
 
 
 
 
intermediate cuneiform(中楔狀骨)
 
 
 
 
 
 
 
lateral cuneiform(外楔狀骨)
 
 
 
 
 
 
 
tarsal bone(跗骨)
近端群跗骨:talus(距骨)calcaneus(跟骨)navicular(舟狀骨)
遠端群跗骨:cuboid(骰子骨)medial cuneiform(內楔狀骨)intermediate cuneiform(中楔狀骨)lateral cuneiform(外楔狀骨)
 
 
 
 
 
 
Metatarsus(蹠骨)
A. 共有五根由大拇指往小五指方向分別為第一蹠骨到第五蹠骨
B.
由前側往後側的構造分別是頭基部
C.
功用在於承受身體重量,身體的重量壓在距骨和跟骨後就往前傳進而分散重量
 
 
 
 
 
 
Phalanges(趾骨)
A. 除大拇指有兩個趾節外,其他皆有三個趾節
B.
共有14塊骨頭

整體分成踝部、蹠部(就是腳板、腳掌較靠近腳趾的區域)、腳趾
• 構成踝部:七塊跗骨(tarsal bone)
• 構成蹠部:五塊蹠骨(metatarsal bone)
• 構成腳趾:趾骨(phalanges),除大拇指兩塊,其餘皆為三塊

1.跗骨(tarsal bone)
2. 蹠骨(Metatarsal bones)
3. 趾骨(Phalanges)
4. 足弓(Arches of the foot)

3 意見:

  1. This is a clear and useful summary of foot anatomy. The breakdown of bones like the talus, calcaneus, and cuneiforms helps explain how the foot supports body weight and movement in a simple way.

  2. A detailed anatomical reference on foot bones and arches, clearly outlining key structures like the talus, calcaneus, and plantar arches with their functional relationships in the foot.

  3. Really detailed breakdown of foot anatomy—especially the way you’ve organized tarsus, metatarsus, phalanges, and all the arches makes it much easier to understand the structure and function of the foot as a whole. Great for anyone studying human anatomy. While going through similar educational notes, I also came across 49s brunchtime results, which presents information in a similarly clear and structured format.
