Where it runs from and to

A muscle is told apart from its neighbours by what it takes hold of at each end, which is also what decides what it does when it shortens.

Action
Carries the trochlea that the tibia rocks on, which is the hinge of the hock.

Written for Vetomica in its own words from the standard reference anatomy of the dog; the books it was checked against are listed below.

Named parts

What to look for on the bone, and what each part is called in the Nomina Anatomica Veterinaria.

Trochlea of the talusTrochlea tali
The grooved proximal surface that the cochlea of the tibia rocks on; the hinge of the hock.Miller 2020, p. 362
Body of the talusCorpus tali
The proximal mass that carries the trochlea.Miller 2020, p. 362
Neck of the talusCollum tali
The waist between body and head.Miller 2020, p. 363
Head of the talusCaput tali
The distal end, which meets the central tarsal bone.Miller 2020, p. 363
Calcanean articular surfacesFacies articularis calcanea
The facets on the plantar side that rest on the calcaneus.Miller 2020, p. 363
Lateral processProcessus lateralis tali
The projection on the lateral side of the body.Miller 2020, p. 363
Tarsal sinusSinus tarsi
The space left between talus and calcaneus where their facets do not meet.Miller 2020, p. 363

What it meets

Trochlea articulates with tibia and fibula (tarsocrural joint).

Bones it articulates with

Joints it forms

  • Tarsocrural joint

Muscles and ligaments that take hold of it

  • Intertarsal joints

Measured on the specimen

What the talus is in contact with in the model itself, with the share of the other structure’s surface it covers. A contact is not always a joint: bones that simply lie against one another are in this list too.

Measured on the left side.
