Which of the following is a secondary anatomical point near the primary striking points?

The elbow joint is considered a secondary anatomical point near the primary striking points due to its accessibility and the specific techniques used in self-defense or law enforcement scenarios. When engaging an assailant, targeting the elbow can disrupt their balance or ability to defend themselves or attack effectively.

It's important to recognize that while the other options such as the throat, solar plexus, and groin are indeed primary striking points due to their vulnerability and impact on an assailant’s ability to continue fighting, they are classified as primary points rather than secondary. The elbow, in contrast, represents an effective secondary target that can be engaged when closer strikes to primary points are not feasible or practical in a confrontation or defensive situation. This classification highlights the importance of understanding various target areas in defensive tactics, emphasizing both immediate and alternative targets for incapacitating an opponent.
