Topography and ultrastructural organization of proprioceptors in the striated parietal muscle of the hagfish, Myxine glutinosa, are described. Due to the topographical location of the afferent nerve terminals four subtypes of proprioceptors are distinguished. Type 1-receptor and type 2-receptor are localized in an encapsulated and lamellated corpuscular organ located along and above the myosepta of the parietal muscle. Type 3-receptor is composed of a complex of free en plaque nerve endings within the dense collagen fibre texture at the site where myoseptum, muscle fascia and body fascia fuse to a raphe. Type 4-receptor resembles type 3 but it is localized in the straight collagen fibre bundles of the myoseptum and the body fascia. A proprioceptive function of the nerve terminals is discussed.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D011434	Proprioception	Sensory functions that transduce stimuli received by proprioceptive receptors in joints, tendons, muscles, and the INNER EAR into neural impulses to be transmitted to the CENTRAL NERVOUS SYSTEM. Proprioception provides sense of stationary positions and movements of one's body parts, and is important in maintaining KINESTHESIA and POSTURAL BALANCE.

D011984	Sensory Receptor Cells	Specialized afferent neurons capable of transducing sensory stimuli into NERVE IMPULSES to be transmitted to the CENTRAL NERVOUS SYSTEM. Sometimes sensory receptors for external stimuli are called exteroceptors; for internal stimuli are called interoceptors and proprioceptors.

D006196	Hagfishes	Common name for a family of eel-shaped jawless fishes (Myxinidae), the only family in the order MYXINIFORMES. They are not true vertebrates.	Hagfish,Myxiniformes,Hagfishe,Hagfishs,Myxiniforme
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D018482	Muscle, Skeletal	A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.
