What bones carry the body’s weight when walking?
Calcaneus and Talus, unless you do something to shift the body weight.
- heels transfer the weight to the metaphalangeal joint
do the inversion action
do the eversion action
do the dorsiflexion action
do the plantar flexion action
a
primarily dorsiflexors of foot and extensors of the toes
b
tibia
c
Fascia lata (surrounding all compartments)
d
Primarily plantar flexors of foot and flexors of the toes
e
Fibula
f
evert the foot
a (posterior view)
gastrocnemius
Action: Plantar flexes foot when knee is
extended, but can also flex the knee since
it crosses the knee joint
Innervation: Tibial nerve L4-S3)
b (posterior view)
plantaris
Action: Assists in knee flexion and plantar
flexion of foot but mainly thought to be
important for proprioception (Body position awareness)
Innervation: Tibial nerve L4-S3)
c (posterior view)
soleus
Action: Plantar flexes the foot, important
postural and locomotor muscle during running
and walking
- also preventing the forward sway of during standing at ease
Innervation: Tibial nerve L4-S3)
d (posterior view)
calcaneal tendon
e (lateral view)
gastrocnemius
Action: Plantar flexes foot when knee is
extended, but can also flex the knee since
it crosses the knee joint
Innervation: Tibial nerve
f (lateral view)
soleus
Action: Plantar flexes the foot, important
postural (balance) and locomotor (running) muscle during running
and walking
- counteracts forward sway during standing at ease
Innervation: Tibial nerve
g (lateral view)
calcaneal tendon
h
Calcaneus
GASTROCNEMIUS (superficial) Action
Plantar flexes foot when knee is
extended, but can also flex the knee since
it crosses the knee joint
GASTROCNEMIUS (superficial) innervation
Tibial Nerve L4-S3)
SOLEUS (superficial) Action
Plantar flexes the foot, important
postural (balance) and locomotor muscle during running
and walking
- counteracts forward swaying during standing at ease
SOLEUS (superficial) Innervation
Tibial nerve L4-S3)
PLANTARIS (superficial) Action
: Assists in knee flexion and plantar
flexion of foot but mainly thought to be
important for proprioception
PLANTARIS (superficial) Innervation
Tibial nerve L4-S3)
a
Plantaris
Action: Assists in knee flexion and plantar
flexion of foot but mainly thought to be
important for proprioception

b
Gastrocnemius medial head
Action: Plantar flexes foot when knee is
extended, but can also flex the knee since
it crosses the knee joint
Innervation: Tibial nerve
c
Gastronemius lateral head
Action: Plantar flexes foot when knee is
extended, but can also flex the knee since
it crosses the knee joint
Innervation: Tibial nerve
