Question

Which spinal nerves go directly to the tissues they supply without forming a plexus?

a. C1 through C4
b. C4 through T1
c. T2 through T12
d. L1 through L5

Answer 1

The spinal nerves that go directly to the tissues they supply without forming a plexus are T2 through T12.

Step-by-step explanation:

The spinal nerves that go directly to the tissues they supply without forming a plexus are:

• c. T2 through T12

Spinal nerves C1 through C5 form the cervical plexus, spinal nerves C4 through T1 form the brachial plexus, and spinal nerves L1 through S4 form the sacral plexus. These plexuses reorganize the axons before they supply the tissues they innervate. However, the spinal nerves of the thoracic region, T2 through T11, are not part of the plexuses and directly supply the tissues they innervate.
