If you are viewing the entire bone, you can differentiate the medial and lateral condyles by noting that the medial condyle is on the side with the head of the femur, and the lateral is on the side with the greater trochanter. If you have only the distal end of the femur available, then you can differentiate the condyles by noting that the medial condyle is longer and the lateral condyle is wider.
Hazard
Keep a green lateral marker to your left, or port, side when proceeding in the upstream.
This is a non-lateral marker. It can indicate a controlled area, such as no wake. It can be an informational marker, a "keep out" marker, or a warning marker (Dam, Rock, etc)
A non-lateral marker indicates the presence of hazards or obstructions that are not related to the direction of navigable waters. They are usually used to mark areas such as underwater pipelines, mooring fields, or designated swim areas. Boaters should navigate around non-lateral markers to avoid these hazards.
A non-lateral marker is a navigation aid that is not used to indicate the sides of a channel. These markers typically provide information such as safe passage, direction, or distance from hazards. Examples include buoys indicating junctions or turns in a waterway.
A non-lateral marker usually denotes hazards or obstructions in the water that you should navigate around. These markers are typically used to indicate safe passage or to warn of potential dangers, and they help maintain safe navigation in waterways.
A non-lateral marker indicates a specific navigation point or reference that is not associated with the lateral boundaries of a waterway. These markers can provide information related to navigation, such as hazard warnings, directions, or points of interest. Unlike lateral markers, which guide vessels along the navigable path, non-lateral markers serve to enhance safety and awareness for mariners. Examples include buoy markers indicating obstructions or informational signs related to marine regulations.
An orange circle non-lateral marker is used in marine navigation to indicate a special area or feature. It typically signifies a specific condition or caution, such as a regulated area, a hazard, or a location where certain activities are restricted. This marker serves to alert vessels to exercise caution and be aware of the unique circumstances in that area.
The orange circle on a non-lateral marker indicates a cautionary area or a special hazard in the water. It is used to alert boaters to exercise caution due to potential dangers such as underwater obstructions, shallow areas, or other navigational hazards. This marker is part of the U.S. Aids to Navigation System and helps ensure the safety of vessels operating in those waters.
A white non-lateral marker with an orange circle is used in marine navigation to indicate a warning or caution area. This marker typically signifies a hazard to navigation, such as a submerged object or a restricted area, and it advises mariners to exercise caution while navigating in that vicinity. The orange circle draws attention and highlights the need for awareness of potential dangers.
The color marker used to warn boaters not to pass between the marker and the shore is typically a red marker. These red markers indicate that boaters should keep them to their right when navigating inland waterways. They are part of the lateral system of buoyage, which helps ensure safe navigation.
The orange diamond Non-Lateral Marker indicates a specific hazard or obstruction in the waterway, such as a rock, a submerged object, or an area where navigation is not advised. It serves to alert boaters to potential dangers that are not marked by standard lateral markers, ensuring safer navigation. These markers are often used in conjunction with other navigational aids to provide comprehensive information about safe passage.
