what are the flexors, extensors, tendons,and ligaments of the elbow? and where are they located?
106441
tendon of Biceps brachii located on radius. Ulner collateral ligament located at juncture of ulna and humerus bones. annular ligament located at junture of fadius and humerus bones.  oblique cord joining ulna and radius.\ntendons:  flexor carpi ulnaris, flexor digitorum profundus, lateral epicondyle, medial epicondyle,extender radialis brevis, extensor carpi radialis longus. there are many more.\nthis gives a general idea.

1. Nerve anatomy: nerves are axons of a neuron, enclosed by myelin, and are part of the peripheral nervous system. Afferent nerves carry sensory information from the body to the dorsak root ganglia of the spinal cord and then to the brain (although cranial nerves go directly to the brain). Efferent nerves carry motor information from the brain to the body (muscles) to contract or relax. \n\n2. Reflex architecture: reflex arc. Sensory info (i.e. pressure) activates specialized sense receptors-->sends afferent signal to dorsal root ganglia of spinal cord-->sends info to interneuron-->sends info to ventral root-->sends efferent info to muscle-->muscle contracts (or relaxes, muscles work in pairs).\n\n3. Embryo forebrain-->telencephalon (cerebral cortex, basal ganglia, and limbic system). Midbrain-->Mesencephalon (thalamus, hypothalamus). Hindbrain-->metencephalon (cerebellum and pons) and myelencephalon (medulla oblongata).\n\n4. Functions of what?\n\n5. Hearing: consists of outer, middle, and inner ear. Outer ear is ear canal, middle ear is the ear drum and 3 smallest bones in body (hammer, anvil and stirrup), inner ear is the cochlea. Sound waves travel through the canal, cause the ear drum to vibrate, which moves the 3 bones, which causes the fluid in the cochlea to move, which activates the hair cells (receptors) that send infor to the auditory cortex in the brain.\nVision: from the outer eye to inner eye, you have cornea, iris, pupil, lens, vitreous humor, and the retina (which has the receptors). Within the retina, you have photoreceptors, bipolar cells, ganglion cells, and amacrine cells. Photoreceptors are rods (light) and cones (color). From the ganglion cells, information gets sent to the primary visual cortex in the brain.\n\n6. The spinal cord is long tube protected by vertebral column. It has white matter (axons or nerves from above definition) on the outside and gray matter (cell bodies) on the inside. The gray matter kind of looks like a butterfly in the spinal cord.\n\n7. Cerebellum: coordinated movement\nThalamus: sensory relay station\nCerebrum: divided into 4 sensory lobes, performs several higher functions such as language, emotion, and memory.\nHypothalamus: controls autonomic nervous system and endocrine systems (4 F's: fighting, feeding, fleeing, and mating...)\nMedulla: controls vital functions (cardiovascular, respiration, and skeletal muscle tone).

Well, I assume you know about finger bones, so I won't go into that...\n\nImagine if you will, right above your elbow, a cluster of muscles with bands of ligament running from them to your fingers.\n\n(extensor digitorum lateralis, extensor digitorum communis, etc)\n\nYou move your fingers, you feel something right in your arm, distal of your elbow, yes?\n\nThose are the muscles that 'pull' if you will, your tendons that run into your digits (fingers).\n\nFlex muscle, pull tendon, finger bends.\n\nI hope this helps,\nGood luck on your project!\n-William

Ligaments are the stringy, strong "ropes" that attach the muscle to the bone.  \n\nI don't know what happens when they are damaged.  Sounds painful if they are damaged.

Wrist flexion muscles are all of the muscles that enable the wrist to move/bend/flex.  I posted a link so that you could better understand them and their functions.

Making a Working Model of an Arm\n\nMaterials needed-\n3 cardboard squares (2sqs =length to lower arm, \n1sq =length of upper arm)\ntape\n1 lg paper clip\n4 long balloons\nstring\nsomeone (to help you poke holes for the paper clips)\n\nTHE BONES:\nCut 2 cardboard sq = length of your lower arm. \nCut 1 cardboard sq = length to your upper arm.\nRoll the cardboard squares tightly; bind ends with tape.\nLabel your rolled squares. Label (1 sq = your upper arm) HUMERUS. Label the other two sqs- RADIUS & ULNA.\n\nTHE JOINT:\nMake a hole through all three "bones" with something sharp. (someone will need to help with this step.)  Unbend a paperclip. Thread it through the holes. Loop the ends.\n\nTHE MUSCLES:\nUsing tape, attach the radius and ulna together by wrapping tape around the free end of both.  Slightly inflate 4 long balloons. Tie knots on both ends.  Tie on the balloon muscles. The first muscle will be the biceps (attached from the humerus to the radius)  Now tie on the balloon for the triceps. The triceps is attached from the one end of the humerus to the other.  BRACHIO-RADIALIS(Forearm Flexors), a muscle situated on the outer (Radial) side of the forearm and lastly BRACHIALIS, muscle covering the front of the elbow. \n\n\n\n[FYI]\nHow many different kinds of joints can you find on your body? Where are the different types located?\nDraw the bones of the arm in the proper location on your body outline diagram. Label the bones. Draw the muscles attached to the arm. Label the muscles.\n\n[MORE TO THINK ABOUT]\nThe bones of the arms and legs are called long bones. The bones of your body are connected with different types of joints. The joints allow your body to move in several different ways. The joint at your elbow is called a hinge joint. Connected to your bones are muscles. Muscles contract to help you move. Muscles work in teams. Every set of muscles has an opposite set of muscles. This helps you to "reverse" or go in the opposite direction.\n\n\nHere are some more links to help you...\n \nHTH.\nTake care.

Biceps- barbell curls, preacher curls, concentration curls\nBarbell curls do standing against something so as to take away any leverage by swinging yourself.\nConcentration curls do standing and do not move your upper arm at all.\nShoulders- overhead press, raises, upright rows\nRaises are to the front, side, and back. Upright rows are shoulder width grip and raise the bar to your neck and back down.\n\nChest- flat & incline bench press, flys

i ruptured a tendon by repeatedly hitting my wrist on a stapler- i also injured myself playing volleyball hitting a ball with the inside of my arm- my doctor told me that the nerves are really close to the bones in your arm- doctors- a good source of medical information!

Pivot Joint: This type of joint allows bones to spin and twist around other bones. There are pivot joints in the neck and the radius part of the elbow.

Are you sure it's bursitis?  Is it red, swollen and warm?  With your hands hanging at your sides and palms facing forward, which side of your elbow hurts (inner/medial or outer/lateral)?  You may just have either medial or lateral epicondylitis which can be caused by either contracted/tight flexor or extensor muscles of the forearm.  Stretching and massage are useful for the treatment of these two conditions as long as it is not in the acute stages of injury.
