Where is the temporomandibular joint?
The TMJ should be classified as a ball and socket joint , as the ball of the condylar head fits into the Glenoid fossa at the base of the skull. This allows for the rotation as well as the lateral movements of the mandible .
See the link below.
It's a modified hinge that contains articular disc.
synarthrosis
In a mammal, the spine is the backbone.
It is also part of a book cover.
How do the skeletal system functions?
Supports body structure, maintains posture, and protects organs. Acts like a framework for organs and provides an attachment site for various muscles within the body
Does a wrist fracture require medical attention?
In my opinion a wrist fracture would definetely require medical attention. There are so many bones in your wrist that it will need a doctor to look at to make sure that you don't need surgery.
How does the skeletal system interact withe the reproductive system?
The nervous system. Sex hormones masculine or feminize the brain and influence sex drive. Hypothalamus regulates timing of puberty; neural reflexes regulates events of sexual responses
Endocrine system. Gonadal hormones exert feedback effects on hypothalamic pituitary axis; a placental hormone promotes maternal hypermetaboilism. Gonadotropins (and GnRH) help sregulate function of gondas.
Cardiovascular system. Estrogen lowers blood cholesterol levels and promotes cardiovascular health in premenopausal women; pregnancy increases workload of the Cardiovascular system. Cardiovascular system transports needed substances to organs of reproductive system; local vasodilation involved in erection; blood transports sex hormones.
Lymphatic system/immunity; developing embryo/fetus escapes immune surveillance (not reject). Lymphatic vessels drain leaked tissue fluid; transport sex hormones; immune cells protect reproductive organs from disease; IgA is present in breast milk.
Respiratory systempregnancy impairs descent of the diaphragm, promotes dyspnea. Respiratory system provides oxygen; disposes of carbon dioxide; vital capacity and respiratory rate increase during pregnancy.
Digestive system digestive organs crowded by devolving fetus; heartburn, constipation common during pregnancy. Digestive system provides nutrients needed for health.
Urinary systemhypertrophy of the prostate gland inhibits urination; compression of the bladder during pregnancy leads to urinary frequency and urgency. Kidneys dispose of nitrogenous wastes and maintain acid-base balance of blood of mother and fetus; seamen discharge through the urethra of the male.
Integumentary systemandrogens activate oil glans which lubricates skin and hair; gonadal hormones stimulate characteristic fat distribution and appearance of pubic and axillary hair; estrogen increase skin hydration; enhances facial skin pigmentation during pregnancy. Skin protects all the organs enclosure; mammary gland secretions (milk) nourish the infant.
Skeletal systemandrogen masculinizes the skeleton and increase bone density; estrogen feminizes the skeleton and maintains bone mass in females. The bony pelvis encloses some reproductive organs; if narrow, the bony pelvis may hinder virginal delivery of an infant.
Muscular systemandrogens promote increase in muscle mass. Abdominal muscle active during childbirth; muscles of the pelvic floor support reproductive organs and aid erection of penis/clitoris
What layer of the tooth is harder than bone?
Teeth are hard because of a crystal molecule they contain called hydroxyapatite. This molecule is part of teeth and bones and is what makes them resistant to bending or compressing. But teeth are harder than bones because the outer layer of enamel contains more hydroxyapatite than anything else in the body
Which vertebra does not have a spinous process?
Cervical vertebrae have a bifurcated spinous process.
What are the four parts of bone and their function?
Marrow:
Produces the blood in the body.
Outer Membrane:
protects the inner part of the bone
Spongy bone:
provides support. Without it, the bone will most likely break.
Compact bone:
More support and protection!
What is fracture of neck of femur?

It is a rock not stone in marrow not in bone in bolster not in bed it is not living but not dead?

What are bones with Latticework structure?
Not a particular bone, but spongy or cancellous bone has a latticework structure. This type of bone is typically found at the ends of long bones as well as making up the bulk of short bones.
Is having an extra rib normal?
The latest research shows that 1 in about 200 people have an extra rib. The preponderance is in females.
What is soft tissue that fills space in spongy bone?
What is the fibrous outer connective tissue covering of a long bone?
The outer sheath of connective tissue of the long bone is known as periosteum. It surrounds the bone in all areas except those in which articulate cartilage is located.
What arwe the common bone names of these bones clavicle sternum mandible patella and scapula?
clavicle = collar bone
patella = knee cap
a vertebra is one of the bones that make up the spine
What are the formation of the endochondral bone?
masses of hyaline cartilage shaped like future bony structures;Grow rapidly for a time and then begin to change extensively.
Is the skull made of one bone or many?
When you're born your skull consists of 44 bones altogether. As you grow some of these bones fuse together. As an adult human there are 20 bones in the skull.
What are the bones the make up the outside part of your ear?
There are no bones in the outer ear. The stiff part of the ear has an underlying cartilage frame. The only bones are the three auditory ossicles of the middle ear.
because whales are mammals so they go through the whole pregnancy thing, with the young growing in the females womb. This means that they need hips to support the unborn young through it's growth.
