Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

2.6K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Actin Treadmilling

8.4K
Actin filaments undergo polymerization and depolymerization from either end. The polymerization and depolymerization rates depend on the cytosolic concentration of free G-actins. The polymerization rate is generally higher at the plus or barbed end, while the depolymerization rate is higher at the minus or pointed end. At a steady state, critical concentration describes the concentration of free G-actin monomers at which the polymerization rate at the plus end is equal to that of the...

Muscles that Move the Leg

3.3K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Diversity of Protists IV01:27

Diversity of Protists IV

270
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Summary

A new millipede species, Eumillipes persephone, has been discovered with a record 1,306 legs, challenging the "thousand feet" name. This finding highlights convergent evolution in super-elongated millipedes.

Area of Science:

  • Zoology
  • Evolutionary Biology
  • Biodiversity

Background:

  • Millipedes are named for having a thousand feet, but no species previously exceeded 750 legs.
  • The new species, Eumillipes persephone, was found deep underground in Western Australia.

Purpose of the Study:

  • To describe a new species of millipede with a record number of legs.
  • To investigate the evolution of extreme body elongation in millipedes.
  • To understand the ecological and evolutionary significance of troglomorphic features.

Main Methods:

  • Field discovery and morphological analysis of a new millipede species.
  • Phylogenomic analysis to determine evolutionary relationships.
  • Comparative analysis with known millipede species.

Main Results:

  • Discovery of Eumillipes persephone, a millipede with 1,306 legs, setting a new world record.
  • E. persephone exhibits troglomorphic features, including eyelessness and lack of pigmentation.
  • Phylogenomic data indicate that extreme elongation has evolved multiple times independently in millipedes (Diplopoda).

Conclusions:

  • The striking similarity between E. persephone and Illacme plenipes is a case of convergent evolution, likely for subterranean locomotion.
  • The discovery underscores the importance of subterranean biodiversity and the need for conservation in regions facing mining threats.
