MC 1 ANATOMY AND PHYSIOLOGY 1 SPINAL COLUMN A.K.A. VERTEBRAL COLUMN OR SPINE, BACKBONE ●​ BONY STRUCTURE EXTENDING FROM THE BASE OF THE SKULL TO THE TAILBONE ●​ MAIN JOB: PROTECTS THE SPINAL CORD -​ CERVICAL - SEVEN -​ THORACIC - TWELVE -​ LUMBAR - FIVE -​ SACRAL - FIVE -​ COCCYX - ONE VERTEBRAL COLUMN SPINAL CORD ●​ A LONG, FRAGILE, TUBE-LIKE STRUCTURE OF NERVOUS TISSUE THAT EXTENDS FROM THE BRAINSTREAM DOWN THE CENTER OF THE BACK, WITHIN THE VERTEBRAL COLUMN ●​ MAIN JOB: COMMUNICATION SYSTEM BETWEEN THE BRAIN AND THE BODY CERVICAL VERTABRAE (TOTAL 7) SIGNIFICANCE OF ATLAS: NODDING, MOVEMENT SIGNIFICANT OF AXIS: ODONTOID DREXESS (DENS) SIDE TO SIDE MC 1 ANATOMY AND PHYSIOLOGY SUPERIOR ARTICULAR FACET (LATERAL MASS) ●​ ARTICULATION (JOIN) ARTICULATES ●​ BIFID SPINOUS PROCESS (TWO) ●​ ODONTOID PROCESS (CENTRAL) ATLAS ●​ SUPPORTS THE WEIGHT OF THE HEAD ●​ LACKS A VERTEBRAL BODY AND A SPINOUS PROCESS ●​ RING-LIKE STRUCTURE FORMEO BY THE AUTERIOR AND POSTERIDE ARCHES AND LATERAL MASSES ●​ ARTICULATES WITH THE AXIS (SECOND CERVICAL VERTEBRAL) VIA THE ODONTOID PROCESS (DENS), ENABLING THE SIDE TO SIDE "NO" MOTION OF THE HEAD ●​ MISALIGNMENTS OR INJURIES TO THE ATLAS CAN AFFECT NECK MOVEMENT AND POTENTIALLY CAUSE DISCOMFORT OR DAIN. AXIS ●​ UNIQUE ODONTOID PROCESS ●​ CRUCIAL FOR ALLOWING THE FIRST CERVICAL (ATLAS C1) TO ROTATE, NG YOUR HEAD "NO" ●​ PRIMARY FUNCTION OF THE AXIS IS TO ALLOW FOR ROTATION OF THE HEAD PIVOT TURNING AROUND C3 - C6 ●​ PRESENCE OF BIFID SPINOUS PROCESS C7 ●​ C7 (VERTEBRA PROMINENS) TYPICALLY HAS A SINGLE, PROMINENT SPINOUS PROCESS ●​ A.K.A VERTEBRA PROMINENS ●​ NOTABLE FOR HAVING A LARGE, EASILY PALPABLE SPINOUS PIECOCESS ●​ CERVICAL NERVE C1, C2, AND C3 CONTROL YOUR FORWARD, BACKWARD AND SIDE HEAD AND NECK MOVEMENTS. THE C2 NERVES PROVIDES SENSATION TO THE UPPER AREA OF YOUR HEAD; C3 GIVES SENSATION TO THE SIDE OF YOUR FACE AND BACK OF HEAD 2 ●​ CERVICAL NERVE 4 CONTROLS YOUR UPWARD SHOULDER MOTION AND IS ONE OF THE NERVES THAT CONTROL YOUR DIAPHRAGM (MUSCLE AT THE BOTTOM OF YOUR RIB CAGE THAT HELPS YOU BREATHE) C4 PROVIDES SENSATION FOR PARTS OF YOUR NECK, SHOULDERS AND UPPER ARMS ●​ CERVICAL NERVE 5 CONTROLS THE DELTOID MUSCLE OF YOUR SHOULDERS AND YOUR BICEPS. C5 PROVIDES SENSATION TO THE UPPER PART OF YOUR UPPER ARM DOWN TO YOUR ELBOW ●​ CERVICAL NERVE 6 CONTROLS THE EXTENSOR MUSCLES OF YOUR WRIST AND IS INVOLVED IN THE CONTROL OF YOUR BICEPS C6 PROVIDES SENSATION OF THE THUMB SIDE OF YOUR FOREARM AND HEAD ●​ CERVICAL NERVE 7 CONTROL VOUR TRICEPS AND WRIST EXTENSORY MUSCLE C7 PROVIDES SENSATION TO THE BACK OF YOUR ARM INTO YOUR MIDDLE FINGER. ○​ C1-C3 - HEAD ○​ C4 - SHOULDER, DIAPHRAGM (BREATHING) ○​ C5 - NECK, ARM, SHOULDER ○​ C6 - THUMBS ○​ C7 - BACK OF ARMS, FINGERS PARALYSIS - NO MOVEMENT PARESTHESIA - NOT TOTALLY PARALYSIS QUADRIPLEGIA(C) - WHOLE BODY PARAPLEGIA(C) - LEFT OR RIGHT HEMIPLEGIA(C) - UP OR DOIV THORACIC (1 TO 12) ●​ CHARACTERIZED BY THEIR ARTICULATION WITH THE RIBS FORMING THE BONY THORAX (WHERE THE 12 RIBS ARE ATTACHED) ○​ T1 TO T7 TRUE ○​ T8 TO T10 FALSE ○​ T11 TO T12 FLOATING ●​ THORACIC CAVITY - HEART, LUNGS WELL, GRAVE, HUKAY, ENCLOSE, STORAGE MC 1 ANATOMY AND PHYSIOLOGY 3 KEY FEATURES OF THE THORACIC VERTEBRAE RIB ARTICULATION ●​ EACH THORACIC VERTEBRAE HAS FACETS ON ITS BODY AND TRANSVERSE PROCESSES THAT ARTICULATE WITH THE RIBS, FORMING COSTOTRANSVERSE JOINTS ●​ SPINOUS PROCESS ●​ THE SPINOUS PROCESSES ARE LONG AND POINT DOWNWARDS VERTEBRAL FORAMEN ●​ THE VERTEBRAL FORAMEN (THE HOLE FOR THE SPINAL CORD) IS CIRCULAR IN THE THORACIC REGION ●​ INTERVERTICAL DISCS ●​ LIKE OTHER VERTEBRAE, THORACIC VERTABRAE ARE SEPARATED BY INTERVERTICAL DISCS THAT ACT AS CUSHION THORACIC KYPHOSIS ●​ THE THORACIC SPINE HAS A NATURAL OUTWARD CURVATURE (KYPHOSIS), WHICH CAN BE EXAGGERATED IN CONDITIONS LIKE KYPHOSIS OR SCHEURMAN'S DISEASE KHYPHOSIS - “KUBA” NATURAL CURVE LORDOSIS - “BUTAD” LUMBAR LUMBAR SPINE ●​ LOCATED IN THE LOWER BACK ●​ SERVES AS A CRITICAL SUPPORT STRUCTURE FOR THE UPPER BODY, ENABLING MOVEMENT AND PROTECTING THE SPINAL CORD ●​ IT CONSIST OF FIVE VERTEBRAE (L1-L15) THAT BEAR A SIGNIFICANT AMOUNT OF WEIGHT AND ENDURE THE STRESS OF LIFTING AND CARRYING SACRAL VERTEBRAE (5) ●​ FUSED INTO THE SACRUM ●​ PRIMARILY FUNCTION TO PROVIDE A STABLE BASE FOR THE SPINE, CONNECT THE SPINE TO THE PELVIS AND PROTECT INTERNAL ORGANS. ●​ THEY ALSO PLAY A CRUCIAL ROLE IN WEIGHT DISTRIBUTION AND ABSORBING SHOCK DURING MOVEMENT PELVIC CAVITY - UTERUS, FALLOPIAN TUBE, URINARY BLADDER - REPRODUCTIVE SYSTEM AND URINARY (ELIMINATION) SYSTEM MC 1 ANATOMY AND PHYSIOLOGY PANGANGANAK - LUMALABAS ANG BATA THE COCCYX OR TAILBONE ●​ PRIMARILY SERVES AS AN ATTACHMENT SITE FOR MUSCLES AND LIGAMENTS PARTICULARLY THOSE OF THE PELVIC FLOOR ●​ IT ALSO PLAYS A ROLE WEIGHT BEARING WHILE SITTING, PROVIDING SUPPORT TO THE ANUS AND INFLUENCING MOVEMENT LIKE DEFECATION (POOP) ●​ ATTACH MUSCLE SPINAL CORD INJURY ●​ SPINAL CORD INJURY (SCI'S) ARE MULTIDIMENSIONAL DISORDERS ARISING FROM DIRECT OR INDIRECT SPINAL CORD DAMAGE. ●​ THE MOST COMMON CAUSE OF SCI IS ACUTE TRAUMA FROM MOTOR VEHICLE COLLISION ALTHOUGH THE CONDITION MAY ALSO ARISE FROM INSIDIOUS ETIOLOGIES SUCH AS MALIGNANCIES AND CHRONIC TUBERCULOUS INFECTION ACUTE - SUDDEN ONSET CHRONIC - EXISTENCE FOR A LONG PERIOD INBORN - PINANGANAK MAYPOON NA SPINAL CORD INJURY (SCI) - ACCIDENTS TB (TUBERCULOSIS) PTB (PHILMONARY TUBERCULOSIS POTT'S DISEASE SPINAL TB PULMONARY TO SPINAL COLUMN - BLOOD STREAM DROPLET INFECTION - COUGH GIBBUS FORMATION - ENLARGEMENT CAUSE OF FATS KAPAG LUMALAKI - COMPRESSION NADIDIINAN SPINAL CORD PRESSURE - FUNCTIONS DISORDER T9 - LOWER EXTRAVITY (PARALYS) URINARY BLADDER (PAGIHI) INCONTINENCE BOWEL MOVEMENT DEFECATION (PAGTAE) SPINAL CORD INJURIES ●​ NUMBNESS, TINGLING, OR A LOSS OF (OR CHANGES IN) SENSATION IN HANDS AND FEET ●​ PARALYSIS (LOSS OF MOVEMENT) ●​ PAIN OR PRESSURE IN THE HEAD, NECK, OR BACK 4 ●​ WEAKNESS IN ANY PART OF THE BODY ●​ UNNATURAL OR UNCOMFORTABLE POSITIONS OF THE SPINE OR HEAD ●​ LOSS OF BLADDER AND BOWEL CONTROL ●​ PROBLEMS WITH WALKING ●​ DIFFICULTY BREATHING ●​ CHANGES IN SEXUAL FUNCTION TYPE OF SPINAL CORD INJURY (SCI) ●​ AN INCOMPLETE INJURY MEANS THE SPINAL CORD IS STILL ABLE TO SEND SOME MESSAGE TO OR FROM THE BRAIN PEOPLE STILL HAVE SOME FEELING, FUNCTION, AND MUSCLE CONTROL BELOW THE SITE OF THEIR INJURY ●​ A COMPLETE INJURY MEANS THAT THERE IS NO NERVE COMMUNICATION BELOW THE INJURY SITE. PEOPLE LOSE MUSCLE CONTROL FEELING OR FUNCTION BELOW THE INJURY ●​ INCOMPLETE HAS FUNCTION ●​ COMPLETE TOTALLY DOESN'T FUNCTION ON SPINAL CORD ●​ CERVICAL SPINAL NERVES (KNOWN AS C1 TO 07) IN THE NECK CONTROL SIGNALS TO THE BACK OF THE HEAD, THE NECK AND THE DIAPHRAGM ●​ THORACIC SPINAL NERVES (KNOWN AS T1 TO T2) IN THE UPPER MID-BACK CONTROL SIGNALS TO THE CHEST MUSCLES, SOME MUSCLES OF THE BACK, AND MANY ORGAN SYSTEMS. ●​ LUMBAR SPINAL NERVE (KNOWN AS L3 to L5) IN THE LOWER MID-BACK CONTROL SIGNAL TO THE LOWER PARTS OF THE ABDOMEN AND THE BACK, THE BUTTOCKS SOME PARTS OF THE EXTERNAL GENITAL ORGANS, AND PARTS OF THE LEGS. ●​ SACRAL SPINAL NERVES (KNOWN AS S1 TO S5) IN THE LOWER BACK CONTROL SIGNALS TO THE THIGHS AND LOVER PARTS OF THE LEGS, THE FEET, MOST OF THE EXTERNAL GENITAL ORGAN AND THE AREA AROUND THE ANUS.
