Let's solve the problem by identifying the requested parts of the circle based on the diagram.

1. **All Radii:** 
   - A radius is a line segment from the center of the circle to any point on the circle.
   - In the diagram, the radii are \( OP \), \( OQ \), \( OR \), and \( OS \).

2. **All Chords:**
   - A chord is a line segment with both endpoints on the circle.
   - In the diagram, the chords are \( PQ \), \( PS \), \( NM \), and \( NR \).

3. **All Secants:**
   - A secant is a line that intersects a circle at two points.
   - In the diagram, the secants are \( \overleftrightarrow{QR} \) and \( \overleftrightarrow{MN} \).

4. **Diameter:**
   - The diameter is a chord that passes through the center of the circle.
   - In this diagram, \( QR \) is the diameter.

5. **Tangent:**
   - A tangent is a line that touches the circle at exactly one point.
   - The tangent in the diagram is \( \overleftrightarrow{MT} \).

6. **Point of Tangency:**
   - The point of tangency is where the tangent touches the circle.
   - The point of tangency in the diagram is \( T \).

Here is the complete solution:

- **All Radii:** \( OP, OQ, OR, OS \)
- **All Chords:** \( PQ, PS, NM, NR \)
- **All Secants:** \( \overleftrightarrow{QR}, \overleftrightarrow{MN} \)
- **Diameter:** \( QR \)
- **Tangent:** \( \overleftrightarrow{MT} \)
- **Point of Tangency:** \( T \)
