What else can I help you with?
A man is shot in the head and the bullet stops just outside the dura mater What is the innermost layer that the bullet has penetrated?
The layers go like this: Skin, Fat, Periosteum, Bone; (Meninges Layers): Dura Mater, Anarchnoid Mater, and Pia Mater. The outermost of the 3 meninges is the Dura Mater, so if the bullet stops just outside of the most external meningeal layer, I would think the answer is that it stops after hitting the bone.
Which form passes through skin but not through bone?
Ultraviolet (UV) radiation can pass through skin, but it is absorbed by bone and does not pass through it. UV radiation is responsible for tanning and sunburn when it penetrates the skin.
What is a longitudinal axis for a bone?
The longitudinal axis of a bone is an imaginary line that runs along the length of the bone from one end to the other. It helps to define the orientation and direction of forces acting on the bone, such as during movement or weight-bearing activities. Understanding the longitudinal axis is important in biomechanics and in the study of bone structure and function.
Why is it the air conduction is longer than the bone conduction?
Air conduction is slower than bone conduction because sound waves need to travel through the air, which is less dense compared to bone. In bone conduction, sound vibrations can directly stimulate the cochlea in the inner ear through the bones of the skull, bypassing the need to travel through the air.
What are the three types of fracture?
The three main types of fracture are: Closed fracture: the bone breaks but does not break through the skin. Open fracture: the bone breaks and protrudes through the skin. Hairline fracture: a small crack in the bone that may be difficult to detect initially.

When the epiphysis closes on a bone the bone can no longer grow in what?
When the epiphysis closes on a bone, the bone can no longer grow in length. The closure of the epiphysis marks the end of longitudinal bone growth, but the bone can still increase in thickness through a process called appositional growth.
What outer layer forms the periosteum of the skull?
Skin of scalp. Layered as followed from superficial to pia mater. skin of scalp peristuem skull bone dura mater-periosteal, meningeal arachnoid mater pia mater
What meninges layer is closest to the bone?
The pia mater.There are 3 layers of meninges: the pia mater adheres to the brain and spinal cord; the dura mater is next to the skull, and the arachnoid mater is in-between the two.
Separates dura mater from bone of vertebra?
The epidural space separates the dura mater from the bone of the vertebra. This space is filled with fat and blood vessels and is where epidural injections are commonly administered to deliver medication for pain relief. The dura mater is a tough, fibrous membrane that surrounds the brain and spinal cord, providing protection and support.
What bone does not contain paranasal sinuses?
Any bone except the skull.
Which Bone has same width and length?
The patella(knee bone) is the closes bone that is as long as it is wide
What protects the dura mater?
The dura mater is protected by the bony skull. It is the tough outermost layer of the meninges that surrounds the brain and spinal cord. It provides physical support and protection for the underlying structures.
What do sponges lack?
Everything except bone.
The area of a long bone where growth in bone length occurs is the?
The growth in bone length of a long bone occurs at the epiphyseal plate, also known as the growth plate. This area is found at the ends of long bones and is responsible for new bone formation during childhood and adolescence, ultimately determining the final length of the bone.
Does the length of time the bone is in vinegar affect how much the bone bends?
