MUSCULOSKELETAL SYSTEM VOCABULARIES - 2 - LESSON 216

We are learning lucrative American medical transcription course freely here in this blog.  We have crossed three systems yet and we are also going to learn all the other six systems of medical terminologies, anatomy, and physiology, and disease conditions, symptoms and signs one by one later from today onwards.  This post explains about musculoskeletal system vocabularies in one or two line format explanation, no way, this subject should be taught in this way only.  You may use any medical dictionary available online for free or any other good one to know more about these explanations in it.

1.  Fontanelle:  This is a soft spot present between the cranial or skull bones of an infant.  This soft spot is due to incomplete formation of bones in the cranium.

2.  Fissure:  This is an opening between bones.  This opening is a narrow opening.

3.  Facial bones:  These are the bones of the face.  The names of the facial bones are lacrimal, mandible, maxillae, nasal, vomer, and zygomatic.

4.  False ribs:  These are the rib bones of the number 8 to 10.

5.  Epiphysis:  This is the end portion of a long bone.

6.  Epiphyseal plate:  This plate is cartilaginous area at the ends of long bones where lengthwise growth takes place.
7.  Disk or disc:  This is a rounded, flat, plate-like structure in the vertebral column.  These are between the vertebrae bones.  Each disk is a fibrocartilaginous substance.
8.  Floating bones:  These are the rib bones from the number 11 to 12.

9.  Foramen:  This is an opening in bones where the blood vessels pass.  Wherefrom only nerves enter and leave outside and inside.

10.  Foramen magnum:  This is the opening in the bone of the occipital bone wherefrom the spinal cord passes.

In the next post, we will learn about more musculoskeletal system vocabularies. Okay.

Come on.

MUSCULOSKELETAL SYSTEM VOCABULARIES - LESSON 215

Now we will see about important musculoskeletal system vocabularies:

1.  Acromion – This is the outward extension of the shoulder bone.  Acromion creates the shoulder tip.

2.  Calcium – The important and major mineral element of the bones.

3.  Cranial bones – The another name for cranial bones are skull bones.  Temporal bone, sphenoid bone, parietal bone, occipital bone, frontal bone, and ethmoid bone are the names of the skull bones.

4.  Articular cartilage – These are the ends of long bones made up of a thin layer of cartilage.

5.  Cancellous bone – This is a porous and trabecular tissue of bones. Cancellous bone is spongy in structure.

6.  Cartilage tissue – This is a flexible and chewy connective tissue.  Cartilage tissue is found on joint surfaces.  This is also found in the embryonic skeleton.

7.  Condyle – This is a knuckle like process.  This structure is present at the end of a bone near the joint.

8.  Acetabulum – This is a socket like rounded structure in the pelvic bone.  In the acetabulum pelvis bone joins with the thigh bone.

9.  Diaphysis – This is long in structure.  This is the middle portion of the bone called shaft.

10.  Compact bone – This is a dense and hard bone tissue.

In the next post, we will learn about more musculoskeletal system vocabularies. Okay.

Hands and Leg Bones - Lesson 214

Bones of the Leg and Foot:

1.  Femur or thigh bone.  Femur is the longest bone in the human body.  This bone has a round-shaped head like structure at its proximal.  This head called femoral head mounts into a socket like depression in the hip bone called acetabulum. The acetabulum was termed for the reason that of its likeness to a rounded cup.

2.  Kneecap or patella.  This bone is a flat in size and small in structure.  Patella is positioned in face of the articulation sandwiched between the femur or thigh bone and one of the lower leg bones called the tibia.  Patella is enclosed or bounded by shielding tendons and seized in position by muscle attachments.

3.  Tibia or shin bone.  Tibia means a music instrument called flute, as this bone resembles that.  Tibia are the largest bones in the legs.  Each tibial bone is present under the skin.  Tibial bones are in front of the leg.  Each tibia joins with the femur bones in each leg at the patella distally with the ankle.  A bony prominence called malleolus is formed by the joining of these bones at the ankle. 

4.  Fibula.  These bones are smaller in structure and two in number.  Fibular bone is hidden under the leg muscle.  It joins at its proximal end with the tibia crossways and also joins at distal end with the tibia and ankle bones.  These to form the bony prominence called lateral malleolus on the outside of the ankle.

5.  Tarsal bones.  These bones are seven in number.  The bones are called ankle bones.  These bones resemble the carpal bones of the wrist, but are larger.  The calcaneus is the largest bone of these seven bones.  Another name of these bones is heel bones.

6.  Metatarsals.  The bones are five in number.  Each metatarsal bone leads to the phalanges of the toes.

7.  Phalanges of the toes.  These bones are five in number.  The two phalanges in the big toe and three bones in the other four toes of the foot.

In the next post, we will learn about musculoskeletal system vocabularies.  Okay.

Hand or Arm Bones and Pelvic Bones - LESSON 213

Hand or Arm Bones and Pelvic Bones: Hand bones are of six types.  They are as follows:
1.  Humerus. 2.  Ulna 3.  Radius. 4.  Carpals. 5.  Metacarpals. 6.  Phalanges. Now we will see in detail about these arm bones one by one. 

1.  Humerus:  The another name of this hand bone is upper arm bone.  This region is the large and rounded head part of the upper arm.  Upper arm bone attaches with the collar bone and the shoulder bone.

2.  Ulna:  The other name of the ulna is medial inferior or lower arm bone.  Elbow bone is the he proximal development of the ulna.  This bone is known as olecranon.

3.  Radius:  This bone is the inferior lateral arm bone.

4.  Carpals:  These bones are wrist bones.  Each wrist consists of four carpal bones in two rows.

5.  Metacarpals:  These bones spread out to the each finger from the carpals. Metacarpals are 5 in number in each hand.

6.  Phalanges:  The other name of these bones are called finger bones.  The phalanx is the singular for the phalanges.  Each finger bone consists of three phalanges.  They are proximal phalanx, middle phalanx, and the distal phalanx.  The thumb only has two phalanges other three phalanges.

Pelvic Bones:

The other name of pelvic bone is called hip bone.  This bone is attached with the sacrum of the spinal column and the thigh bone.  Pelvic bones give hold to the chest bone.  Each pelvic bone is a combination of three bones, such as the ilium, the ischium, and the pubis.  We will see about each of these bones one by one.

Ilium:  This is the topmost region of the pelvic bone.  Ilium is the largest bone in the pelvis.  The two divisions of the ilium do not meet dorsally, but these two divisions of the ilium are attached to the sacral bone on each side.  This connection is very strong and looks like one bone. The name of this part is called sacroiliac.  Iliac crest is the greater part of the iliac bone and packed up of red bone marrow.  Abdominal wall muscles are attached to the ilium.

Ischium:  The latter part of the pelvic bone is called ischium.  Isch/o means rear or back.  These bones and the muscles attached to these bone helps us to take the weight off our feet.

Pubis:  This part of the pelvic bones are the frontal or forward portion of the pubis bone.  Pubic bone consists of two parts. The two parts of the pubis called pubes attach together through a cartilaginous disk.  This area of union is called pubic symphysis.  Pelvic girdle is the part of the pelvic bone within the ring of pelvic bone forms the pelvic cavity where the urinary bladder, sigmoid colon, anus, and male and female reproductive organs are present.

In the next post, we will learn about Leg and Foot bones.  Okay.
