Major Superficial Muscles

Skeletal Section

Digestive System

Muscles are made up of thousands of fibres which flex and extend to provide movement. The major Superficial muscles are shown in the diagram above and are provided as a reference. Each muscle originates from a stable part of the skeleton to which it is attached. ( see skeletal link above) Most muscles work in pairs or groups . To enable the horse to move, one muscle must shorten (contract) while its opposing muscles lengthens (relaxes). When muscles work in this way they are known as 'antagonistic pairs'
