Proprioception And Reflexes

Proprioception And Reflexes

Proprioception And Reflexes
We are aware of the orientation of our limbs with respect to one another, we can perceive the movements of our joints and we can accurately assess the amount of resistance (force) that opposes the movements we make. This ability is called proprioception. The three qualities of this modality are position, movement and force. The receptors or proprioceptors that mediate this modality are principally found in the joint capsules (joint receptors), muscles (muscle spindles) and tendons (Golgi tendon organs).
The joint capsule is compressed or stretched when the joint moves, and mechanoreceptors within it signal the position of the joint, as well as the direction and velocity of the movement. Individual receptors respond to the position of the joint, as well as the direction and the velocity of the movement, but not the force. The receptor types found in the joint capsule are Ruffini-type (slowly adapting) stretch receptors (Chapter 55).
Proprioception And Reflexes

Each muscle contains a number of small muscle fibres (intrafusal muscle fibres: 15–30 μm in diameter and 4–7 mm in length) that are thinner and shorter than the ordinary muscle fibre (extrafusal muscle fibres: 50–100 μm in diameter and varying in length from a few millimetres to many centimetres). Several intrafusal fibres are grouped together and encased in a connective tissue capsule, called the muscle spindle, a specialized receptor that responds to the stretch of a muscle (Fig. 60a). Muscle spindles lie in parallel to the extrafusal muscle fibres and are elongated when the muscle is stretched. The primary sensory innervation of the muscle spindle consists of afferent fibres which wind themselves around the centre of the intrafusal muscle fibres (annulospiral ending). These are large myelinated fibres (group Ia afferents). These endings are called primary sensory endings and, when excited, they evoke a monosynaptic stretch reflex involving an excitation of the homonymous α-motor neurones and reciprocal inhibition of the heteronymous α-motor neurones (Fig. 60b).

Masseter, Temporalis and Infratemporal Fossa

Masseter, Temporalis and Infratemporal Fossa


Masseter, Temporalis and Infratemporal Fossa
Masseter
Masseter (Fig. 7.29) attaches along the length of the zygomatic arch and its fibres slope downwards and backwards to the lateral surface of the ramus of the mandible adjacent to the angle (Fig. 7.31). This muscle is a powerful elevator of the mandible and is easily palpated when the teeth are clenched. It is supplied by the masseteric branch of the mandibular (V3) division of the trigeminal nerve.
