Which regions of the body are supplied by plexuses and which are served by intercostal nerves?
Plexuses primarily supply the limbs and certain body regions, with major examples being the brachial plexus for the upper limb, the lumbar plexus for the lower limb, and the sacral plexus also serving the lower limb and pelvic area. In contrast, intercostal nerves supply the thoracic wall, including the intercostal muscles, skin over the thorax, and parts of the abdominal wall. These nerves arise from the thoracic spinal nerves and do not form plexuses.
What the upper limbs and lower limbs have?
Upper limbs have arms, hands, and fingers, while lower limbs have legs, feet, and toes. Both upper and lower limbs are important for various activities such as movement, balance, and fine motor skills.
What nerve runs from tips of fingers to shoulder?
The brachial plexus is a network of nerves that runs from the spinal cord to the shoulder, arm, and hand. It is responsible for transmitting signals between the spinal cord and the upper limbs, including the fingers.
What region surrounding the crease in the skin at the junction of the upper leg with the trunk?
The region surrounding the crease in the skin at the junction of the upper leg with the trunk is called the inguinal region. This area is important for lymphatic drainage, blood vessels, and nerves that supply the lower limbs. It is also a common site for hernias to occur due to the natural weakness in the abdominal wall in this area.
What is the portion of the body that includes the upper and lower limbs?
appendicular.
What is the spinal cord feature associated with the leash of nerves supplying the upper limbs?
The brachial plexus is the spinal cord feature associated with the leash of nerves supplying the upper limbs.
The cervical enlargement contains nerves that supply the?
The cervical enlargement contains nerves that supply the upper limbs, shoulders, and neck muscles. It is responsible for coordinating motor function in this area of the body.
What organs are affected by leprosy?
Skin, nerves, Limbs, Eyes, mucosa of Upper respiratory tract.
What the upper limbs and lower limbs have?

Why are biceps and triceps useful in football?
You can not run without moving your upper limbs in contra lateral positions to lower limbs. (Try to run with upper limbs tied to your body.) Importance of running in football needs no comment. Also imagine the goalkeeper not using his upper limbs!
Why are the bones of the lower limbs larger and heavier than upper limbs?
The bones of the lower limbs are larger and heavier than the bones of the upper limbs because they must support the body's weight and provide stability during activities like walking, running, and jumping. The lower limbs also have larger muscle groups attached to them, which contribute to their increased size and strength compared to the upper limbs.
What is the significance of the spinal cord enlargement?
There are two the cervical and the lumbar. They are enlarged because the cervical gives rise to nerves in the upper limbs and lumbar in the lower limbs thus they have more nerves running to and from which accounts for the enlargements.
Which spinal nerves comprise the brachial plexus and the lumbosacral plexus?
The brachial plexus is formed by the spinal nerves C5-T1, while the lumbosacral plexus is formed by the spinal nerves L1-S4. These plexuses are networks of nerves that supply motor and sensory innervation to the upper and lower limbs, respectively.
What terms are used to refer to the arms and legs?
The arms are often referred to as upper limbs or upper extremities, while the legs are referred to as lower limbs or lower extremities.
What nerve runs from tips of fingers to shoulder?
