Ambulacral Echinoderms can have ambulacral parts that include ossicles, plates, spines, and suckers. For example, sea stars or star fish have an ambulacral groove on their oral side (underside).This ambulacral groove extends from the mouth to the end of each ray or arm. Each groove of each arm in turn has four rows of hollow tube feet that can be extended or withdrawn.Opposite the ambulacral groove is an ambulacral ridge on the aboral side of each ray, known as an ambulacrum.chinoderms can have ambulacral parts that include ossicles, plates, spines, and suckers. For example, sea stars or star fish have an ambulacral groove on their oral side (underside).

Paramecium The paramecium use their oral groove's cilia to sweep down food particles into the mouth pore. The mouth pore transferees the food molecules into the gullet, which forms two food vacuoles that circulate around the cytoplasm. Organic molecules are then digested and absorbed. Molecules that are not digested.

Case reportPeroneal retinaculum injury: An unusual cause of ankle pain There is considerable anatomical variation in the depth of the peroneal groove. The tendons may be more prone to sublux in persons with a shallow groove, and hence the pre- disposition to retinaculum injury in these individuals.1 The superior retio naculum forms part of the tendon sheath at the peroneal groove.

Groove (music) In music, groove is the sense of propulsive rhythmic feel or sense of swing. In jazz, it can be felt as a persistently repeated pattern. It can be created by the interaction of the music played by a band's rhythm section (e.g. drums, electric bass or double bass, guitar, and keyboards).

Morphopedics The anterior and superior part of the labrum is the mostly innervated portions consisting of free nerve endings and sensory nerve end organs. These structures are the receptors of pain, pressure, deep sensation, and temperature sensation from the labrum directing the source of hip pain to a labral tear.he hip labrum Is a dense connective tissue and fibrocartilaginous structure surrounding the bony acetabular rim. The labrum is continuous circumferentially and inferiorly, it bridges across the acetabular notch by the transverse acetabular ligament connecting the anterior and posterior horns of the labrum.

- On the floor of the oral cavity is the tongue, a large collection of muscles covered by mucous membrane. The dorsal surface of the tongue is divided into an anterior 2/3 or oral part and a posterior 1/3 or pharyngeal part by a prominent.The muscles of the tongue can be divided into extrinsic and intrinsic muscles. Extrinsic muscles serve to move the tongue about in the oral cavity.he dorsal surface of the tongue is divided into an anterior 2/3 or oral part and a posterior 1/3 or pharyngeal part by a prominent.

Ambulatory Electrocardiogram Ambulatory EKG monitoring is done to: 1  Look for and record irregular heartbeats that come and go or happen during certain activities. 2  Find out what is causing chest pain or pressure, dizziness, or fainting. 3  Look for poor blood flow to your heart muscle.  Check to see if treatment for an irregular heartbeat is working.

What is ambulacral system ? Best Answer: VASCULAR SYSTEM NOT AMBULACRAL SYSTEM!!!! Echinoderms are characterized by a unique coelomic water vascular system. This is a hydraulically controlled system consisting of a circumoral ring around the esophogus with connecting radial canals each leading to an ambulacrum.The radial canals in crinoids run along each arm into an ambulcral groove and tube feet.f the radial canals run down the ambulacral grooves and are not covered by plates then the system is considered open, if the radial canals are primarily internal and externalized through pores, the system is closed.

- Rows of tube-feet lie within these grooves. The ambulacral grooves are supported by a definite arrangement of ossicles: two rows of rod-shaped ambulacral ossicles form the V-shaped ambulacral groove itself. Where these meet they form the prominent ambulacral ridge on their inner surface.bove: the oral surface of a starfish. The mouth is visible in the centre of the disc, in the middle of a circular or pentagonal peristomial membrane or peristome (shown in darker orange). A groove, called the ambulacrum, extends from the tip of each arm toward the peristome.

Posterior cruciate ligament Posterior cruciate ligament. The posterior cruciate ligament (PCL) is one of four ligaments that hold the knee in place and provide added stability. More specifically, the PCL helps to ensure proper alignment of the femur and tibia, also called the thighbone and shinbone.Ligaments are fibrous tissue that usually connect bones.ccording to Medline Plus, the PCL is the strongest ligament in the knee. An injury to the posterior cruciate ligament may or may not require surgery, depending upon the severity of the injury, age of the patient, and whether other ligaments and cartilage are involved.

Posterior Cruciate Ligament Injury The posterior cruciate ligament (PCL) is a ligament within the knee. Ligaments are tough bands of tissue that connect bones. The PCL -- similar to the anterior cruciate ligament (ACL) -- connects the thigh bone (femur) to your shin bone (tibia). Although it is larger and stronger than the ACL, the PCL can be torn. PCL tears make up less than 20% of injuries to knee ligaments. Injuries that tear the PCL often damage some of the other ligaments or cartilage in the knee, as well. In some cases, the ligament can also break loose a piece of underlying bone.

Posterior cruciate ligament Posterior cruciate ligament. The posterior cruciate ligament (or PCL) is one of the four major ligaments of the knee. It connects the posterior intercondylar area of the tibia to the medial condyle of the femur. This configuration allows the PCL to resist forces pushing the tibia posteriorly relative to the femur.

Bearing Up: What You Need To Know Before You Buy That Next Set Of Engine Bearings This extends the bearing’s oil groove from the upper bearing past the parting line to ensure a better supply of oil to the loaded portion of the bearing in the cap. Full groove bearings should never be used in a performance application because this reduces bearing surface area and increases the load on the remaining portion of the bearing.
