Mechanoreceptors: any of the sense organs that respond to vibration, stretching, pressure, or other mechanical stimuli. Muscle Spindles: a proprioceptor that conveys information on the state of muscle stretch or length, important in the reflex mechanism that maintains body posture.
Which type of joint includes the sutures of the skull?
fibrous joint
A suture is a type of fibrous joint that is only found in the skull (cranial suture). The bones are bound together by Sharpey’s fibres. A tiny amount of movement is permitted at sutures, which contributes to the compliance and elasticity of the skull. These joints are synarthroses.
What is forearm Magnum?
The foramen magnum (Latin: great hole) is a large, oval-shaped opening in the occipital bone of the skull. It is one of the several oval or circular openings (foramina) in the base of the skull. Studies on the foramen magnum position have shown a connection to the functional influences of both posture and locomotion.
Why is the foramen magnum important?
The foramen magnum functions as a passage of the central nervous system through the skull connecting the brain with the spinal cord.
