extensor digitorum longus, the extensor hallucus longus and the peroneus tertius muscles help dorsi flexion
tibialis anterior
Dorsi flexion is the movement of bringing your foot up towards your knee. The opposite movement is planter flexion which is moving your foot away from your knee as if standing on your tip toes.
A permanent planter flexion, also known as equinus deformity, is a condition where the foot is positioned in a downward flexed position, making it difficult to bring the toes up toward the shin. This can result from various factors, including neurological conditions, muscle imbalances, or trauma. It can lead to mobility issues and may require treatment options such as physical therapy, orthotics, or surgery to restore normal foot function.
The prime movers for inversion of the foot are the tibialis anterior and tibialis posterior muscles. The tibialis anterior is located on the front of the lower leg and it helps to invert the foot by pulling the foot upwards and inwards. The tibialis posterior is located deep in the calf and it assists in inversion by pulling the foot inwards.
plantar flexion
Foot flexion refers to the bending of the foot downward, while foot extension refers to the movement of the foot upward. Flexion has a greater range of motion compared to extension, allowing for more movement in activities like walking and running. However, excessive flexion or extension can lead to strain or injury in the foot, affecting overall foot health. It is important to maintain a balance between flexion and extension to prevent issues such as plantar fasciitis or Achilles tendonitis.
The bending of the foot at the ankle has been argued which movenment is flexion and which extendtion. So to avoid arguemnet both lifting and lowerng the foot at the ankle was termed flexion. Dorsiflexion and plantarflexion respectively.
Foot extension and flexion are movements that occur at the ankle joint. Foot extension involves pointing the toes away from the body, while foot flexion involves pulling the toes towards the body. In terms of range of motion, foot extension typically has a greater range compared to foot flexion. This is because the muscles and tendons responsible for foot extension are generally stronger and more flexible than those involved in foot flexion. Biomechanically, foot extension is important for activities such as walking, running, and jumping, as it helps propel the body forward and provides stability during these movements. Foot flexion, on the other hand, is crucial for activities like squatting and climbing, as it helps maintain balance and control the position of the foot. Overall, both foot extension and flexion play important roles in the overall function and movement of the foot and ankle joint.
Dorsiflexion is the foot movement that bends the foot upward toward the leg. It is controlled by muscles in the front of the lower leg, such as the tibialis anterior. Dorsiflexion helps in activities like walking, running, and standing on tiptoes.
Plantar flexion is a movement of the foot which takes the toes further away from the shin. The foot falls down at the ankle. It occurs when you stand on your tiptoes.
Flexing or moving the sole of your foot.
Fibularis Longus and Fibularis Brevis are both Plantar Flexes, page 222 of the Human Anatomy & Physiology Lab Manual (Elaine N. Marieb and Susan J. Mitchell. The prime movers for plantar flexion are the gastrocnemius and soleus (known together as the triceps surae). The gastrocnemius is the larger of the two muscles and is the one visible if you "flex" the calf by lifting your heel off the ground and putting pressure on the front of the foot.
