The Five Sense Organs in Human Beings The sense organs — eyes‚ ears‚ tongue‚ skin‚ and nose — help to protect the body. The human sense organs contain receptors that relay information through sensory neurons to the appropriate places within the nervous system. Each sense organ contains different receptors. • General receptors are found throughout the body because they are present in skin‚ visceral organs (visceral meaning in the abdominal cavity)‚ muscles‚ and joints. • Special receptors include

LIGAMENTS Anterior and posterior longitudinal ligament: Both these ligaments start from the skull to sacrum and are attached on the anterior and posterior surface of the vertebral bodies and intervertebral disks. Ligamentum flavum:It connects the laminae of two adjacent vertebrae and is pierced during spinal anesthesia or lumber puncture. Interspinous & supraspinous ligament (ligament nuchae):It connects the supraspinous and intraspinous

joint and associated ligaments is dangerous. The people who believe this are often those associated with the treatment of squat injuries‚ so they have a rather narrow view of the exercise. However‚ studies on the squat and the associated forces on the knee show that it is indeed safe. The strengthening of the muscles around the knee helps to stabilise it in everyday activity and sport alike. Similarly‚ if overtraining isnt present‚ it will also have advantages on the ligaments of the knee. In particular

Anatomy of the Eye More from this chapter | PDF version (print quality) Video lecture | Anatomy Questions | Pimp Questions Anatomy Flashcards | | Before discussing conditions affecting the eye‚ we need to review some basic eye anatomy. Anatomy can be painful for some (personally‚ I hated anatomy in medical school) so I’m going to keep this simple. Let us start from the outside and work our way toward the back of the eye.Eyelids The eyelids protect and help lubricate the eyes. The
