What type of vertebrae have openings in their transverse processes that guide the vertebral arteries up toward the brain?
Kaylis [27]

Answer:

Cervical vertebrae

Explanation:

The cervical vertebrae are the vertebrae present in the neck region. All cervical vertebrae are characterized by the presence of three foramina. One is the vertebral foramen and the rest two are called transverse foramina. Each transverse process of each cervical vertebrae contains a transverse foramen. The vertebral artery and the related vein and nerve fibers pass through the transverse foramina. Among the all cervical vertebrae, the transverse processes and transverse foramina of the atlas are relatively larger.

Answer:

the thin filaments are pulled away from one another, thereby reducing their ability to interact with myosin

Explanation:

The myofibril is the basic unit of a muscle cell. Each myofibril is composed of contractile units known as sarcomeres which may contain two different types of myofilaments: thick myofilaments and thin myofilaments. The thick filaments are known to have a constant length, and they consist especially of myosin proteins. These filaments (thick) do not extend to the ends. On the other hand, the thin filaments extend in from each end, and they are mainly composed of actin proteins that serve as tracks for the movement of myosin proteins.
