My Captain!” is a symbol for the end of Civil War and Lincoln’s death. While the voyage symbolizes the Civil War, it may also symbolize Lincoln’s life. When the speaker says that the anchored ship is safe and sound, Whitman refers to the country being out of war and in a state of peace.

My Captain!” The speaker compares President Lincoln to the captain of a ship and then refers to him as my captain, emphasizing his own personal connection to the president. The poem is not titled “Our Captain”; rather, the speaker seems to feel that President Lincoln is his captain in particular.

My Captain!” by Walt Whitman, the speaker is referring to Abraham Lincoln who has tragically died. The speaker both celebrates that the ship has arrived safely and mourns the death of its leader.

(Entry 1 of 5) intransitive verb. 1 : to fall in or as if in a faint —usually used with over keeled over from exhaustion. 2 of a boat or ship : to heel or lean precariously.

Prow came into English from the Greek word prōira, from a base meaning “in front.” Prow typically refers to the front part of a ship — the pointy bit that cuts through the water. You might see the prow of a ship approach the harbor through the fog.

transitive verb. : to charge with or show evidence or proof of involvement in a crime or fault.

example, flying birds have a keel—a ridge on the sternum, or breastbone, which is a main site of attachment for flight muscles. Ratites do not possess this keel, and its absence is one reason why the group’s muscles are unsuitable for flight.

The keel is basically a flat blade sticking down into the water from a sailboat’s bottom. It has two functions: it prevents the boat from being blown sideways by the wind, and it holds the ballast that keeps the boat right-side up.

Pygostyle describes a skeletal condition in which the final few caudal vertebrae are fused into a single ossification, supporting the tail feathers and musculature. In modern birds, the rectrices attach to these.

Birds have a lightweight skeleton made of mostly thin and hollow bones. The keel-shaped sternum (breastbone) is where the powerful flight muscles attach to the body. Birds are the only vertebrate animals to have a fused collarbone called the furcula or wishbone and a keeled breastbone.

Birds take oxygen into their body tissues when they breathe in and when they breathe out. So, for every one bird breath, humans would need to take two. This makes birds super-efficient breathers. Amazing!

Ok, time for a quick anatomy lesson: Despite what you may have heard, bird knees do not bend backward. Given the role of the knee in locomotion, it’s not even clear how such a reversal could evolve after the initial “knee bend” direction was settled upon several hundred million years ago.

their back legs are like our feet, their “backwards knee” is actually an ankle, and their front legs look remarkably like a human arm. As to why both knees bend backwards, well, they probably based the gaits of animals like dogs.

The joint that you might consider to be their “knee” is actually their ankle joint. Their knee is higher up on the leg, and does bend in the same direction ours does. This means that birds walk with their weight on just their toes!

Your knee can also get bent backward from contact. If something or someone hits the front of your knee, the joint can be pushed back too far. That can injure the ligaments and other parts of the knee. Sometimes your foot can get caught in something and cause you to fall.

The posterior cruciate ligament keeps the tibia from moving backwards too far. An injury to the posterior cruciate ligament requires a powerful force. A common cause of injury is a bent knee hitting a dashboard in a car accident or a football player falling on a knee that is bent.

During hyperextension, the knee joint bends the wrong way, which often results in swelling, pain and tissue damage. In severe cases, ligaments such as the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), or popliteal ligament (the ligament along the back of the knee) may be sprained or ruptured.

Top 5 Tips for Preventing Knee Hyperextension

1. Make Use of Motion Intelligence Device.
2. Use of Knee Braces.
3. Engage in Strengthening Exercise.
4. Warming-Up before Athletic Events.
5. Always Take Time to Cool Off after Every Sporting Event.

Hyperextension occurs when the knees are pushed too far back, usually from over-stretching of the ligaments. Because of this, the Posterior cruciate ligament is prone to injury. The PCL is the strongest ligament in the knee and is pretty crucial for a ballet dancer.

If you have previously hyperextended your knee, your knee may feel weak and unstable. Wearing a knee brace for knee hyperextension can help prevent your knee from overextending in the wrong direction. Athletes looking to protect their knee from hyperextension should protect their knee with a brace like the Bionic.
